New submission from Lenard Lindstrom <le...@telus.net>:
http://www.python.org/doc/2.6/glossary.html
The decorator entry in the Python 2.6 documentation incorrectly
describes a decorator as "merely syntactic sugar". It is not, as this
example shows:
>>> def decorator(f):
f.prev = globals()[f.__name__]
return f
>>> func = 0
>>> def func():
pass
>>> func = decorator(func)
>>> func.prev
<function func at 0x00C748F0>
>>> func = 0
>>> @decorator
def func():
pass
>>> func.prev
0
This distinction could be useful in building multi-methods, for example.
