One thing I added awhile back to PEP 318 as an open issue is that for ease
of writing wrappers the func_name attribute of a function object should be
writable. For example, in situations where the decorator returns a new
function object (often, I would think) it would really be nice if that new
function object had the same name as the undecorated function. Consider:
def a(func):
def _inner(*args, **kwds):
return func(*args, **kwds)
return _inner
@a
def func(*args, **kwds):
print args
print kwds
print "func's name:", func.func_name
I realize you can use new.function() to create a new function object, but
that seems like a fair amount of extra complexity just to change the
function's name. I'd prefer it if the decorator could be written as:
def a(func):
def _inner(*args, **kwds):
return func(*args, **kwds)
_inner.func_name = func.func_name
return _inner
That fails because func_name is readonly. Any chance this restriction can
be loosened up?
