To calculate the tenth Fibonacci number, you should really only need to calculate the preceding Fibonacci numbers, but this implementation somehow needs a whopping 177 calculations. It gets worse quickly: 21891 calculations are needed for fibonacci(20) and almost 2.7 million calculations for the 30th number. This is because the code keeps recalculating Fibonacci numbers that are already known.
The decorate() proposal was that no new syntax be implemented -- instead a magic function that used introspection to manipulate the following function. Both Jp Calderone and Philip Eby produced implementations of functions that did this. Guido was pretty firmly against this -- with no new syntax, the magicness of a function like this is extremely high:

A still life is a work of art depicting mostly inanimate subject matter, typically commonplace objects—which may be either natural (food, flowers, plants, rocks, or shells) or man-made (drinking glasses, books, vases, jewelry, coins, pipes, and so on). With origins in the Middle Ages and Ancient Greek/Roman art, still life paintings give the artist more leeway in the arrangement of design elements within a composition than do paintings of other types of subjects such as landscape or portraiture. Still life paintings, particularly before 1700, often contained religious and allegorical symbolism relating to the objects depicted. Some modern still life breaks the two-dimensional barrier and employs three-dimensional mixed media, and uses found objects, photography, computer graphics, as well as video and sound.
Hegel recognized the failure of attaining a universal concept of beauty and, in his aesthetic essay, wrote that painting is one of the three "romantic" arts, along with Poetry and Music, for its symbolic, highly intellectual purpose.[11][12] Painters who have written theoretical works on painting include Kandinsky and Paul Klee.[13][14] In his essay, Kandinsky maintains that painting has a spiritual value, and he attaches primary colors to essential feelings or concepts, something that Goethe and other writers had already tried to do.
After having shot a man in a Santa Fe bar, the famous artist Jim Stegner served his time and has since struggled to manage the dark impulses that sometimes overtake him.  Now he lives a quiet life. . . until the day that he comes across a hunting guide beating a small horse, and a brutal act of new violence rips his quiet life right open. Pursued by men dead set on retribution, Jim is left with no choice but to return to New Mexico and the high-profile life he left behind, where he’ll reckon with past deeds and the dark shadows in his own heart. 
As with many construction jobs, those who successfully complete apprenticeships best-position themselves for successful painting careers. For painters, apprenticeships can last up to four years. Apprentices must have a high school diploma or its equivalent before they are eligible to complete the requisite 144 hours of technical instruction and 2,000 hours of paid, on-the-job training. Common lessons include aesthetics, such as how to adequately match colors, as well as using and caring for painting tools and equipment, safety practices, application techniques and wood finishing. Prospective painters may also choose to attend two-year technical schools that offer courses linked to union and contractor organization apprenticeships. Credits gained from apprenticeships typically count toward an associate degree.

Just take a look at the code again. In the if/else clause we are returning greet and welcome, not greet() and welcome(). Why is that? It’s because when you put a pair of parentheses after it, the function gets executed; whereas if you don’t put parenthesis after it, then it can be passed around and can be assigned to other variables without executing it. Did you get it? Let me explain it in a little bit more detail. When we write a = hi(), hi() gets executed and because the name is yasoob by default, the function greet is returned. If we change the statement to a = hi(name = "ali") then the welcome function will be returned. We can also do print hi()() which outputs now you are in the greet() function.
There is some history in Java using @ initially as a marker in Javadoc comments [24] and later in Java 1.5 for annotations [10], which are similar to Python decorators. The fact that @ was previously unused as a token in Python also means it's clear there is no possibility of such code being parsed by an earlier version of Python, leading to possibly subtle semantic bugs. It also means that ambiguity of what is a decorator and what isn't is removed. That said, @ is still a fairly arbitrary choice. Some have suggested using | instead.
... the keyword starting the line that heads a block draws a lot of attention to it. This is true for "if", "while", "for", "try", "def" and "class". But the "using" keyword (or any other keyword in its place) doesn't deserve that attention; the emphasis should be on the decorator or decorators inside the suite, since those are the important modifiers to the function definition that follows. ...
Surrealism is a cultural movement that began in the early 1920s, and is best known for the visual artworks and writings of the group members. Surrealist artworks feature the element of surprise, unexpected juxtapositions and non sequitur; however, many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost, with the works being an artifact. Leader André Breton was explicit in his assertion that Surrealism was above all a revolutionary movement.
You saw that, to define a decorator, you typically define a function returning a wrapper function. The wrapper function uses *args and **kwargs to pass on arguments to the decorated function. If you want your decorator to also take arguments, you need to nest the wrapper function inside another function. In this case, you usually end up with three return statements.

Modern artists have extended the practice of painting considerably to include, as one example, collage, which began with Cubism and is not painting in the strict sense. Some modern painters incorporate different materials such as sand, cement, straw or wood for their texture. Examples of this are the works of Jean Dubuffet and Anselm Kiefer. There is a growing community of artists who use computers to "paint" color onto a digital "canvas" using programs such as Adobe Photoshop, Corel Painter, and many others. These images can be printed onto traditional canvas if required.
