The wrapper is a generic callable object. It works by generating a copy of the wrapper with the right signature and by updating the copy, not the original.

A caller function is any function like this:: def caller(func, *args, **kw): # do something return func(*args, **kw) Here is an example of usage: >>> @decorator ... def chatty(f, *args, **kw): ... print("Calling %r" % f.__name__) ... return f(*args, **kw) >>> chatty.__name__ 'chatty' >>> @chatty ... def f(): pass ... >>> f() Calling 'f' decorator can also take in input a class with a .caller method; in this case it converts the class into a factory of callable decorator objects.
