[Python-Dev] PEP 318: Suggest we drop it

- There is no universally liked syntax (or even a universally 
_tolerable_ syntax)
- decorators will incosistently retain or drop docstrings (this may even 
be the most appropriate thing to do)
- a "decorated" function may have an arbitrarily distant relationship 
with the function as implemented in the def statement (this is a killer)
- if you want to decorate a single function two separate ways, you're 
back to 2.3 syntax - say, one that logs, checks parameters, etc., and 
the "internal" optimal version. None of the decorator syntaxes 
facilitate this.

Because of all these issues, I think we should drop PEP 318.

The 2.3 form seems more reasonable all the time:

def __func( self ):
spanishInquisition = mydecorator( __func )
spanishInquisition.__doc__= """Something unexpected"""

parrot = otherdecorator( __func )
parrot.__doc__ = """And now for something completely different"""

Are any of the syntaxes enough better to justify the irritation or 
divisiveness of including it?

Syntactic sugar causes cancer of the semicolon, indeed...
