Re: [Python-Dev] properties with decorators (was: code blocks using 'for' loops and generators)

well, I think some people desire a more streamlined way of writing code
like:
def f(...)

def g(...)

x = h(...,f,g)
[property, setting up callbacks etc are cases of this]

I think properties are the most used case where this kind of thing would
be nice.  Though the only thing that I've ever had a gripe with
properties is that I didn't like the trailing property() call - which is
why I wrote a property helper decorator (a use can be seen in [1]).  But
my needs are small, so maybe this kind of thing isn't sufficient for
those who write hundreds of properties.

I'm still trying to decide if the following is an elegant solution to defining 
properties, or a horrible abuse of function decorators:

def as_property(func):
  return property(*func())
class Example(object):
  @as_property
  def x():
    def get(self):
      print "Getting!"
    def set(self, val):
      print "Setting!"
    def delete(self):
      print "Deleting!"
    return get, set, delete
Cheers,
Nick.
