On and off, I've been looking for an elegant way to handle properties using decorators.

This isn't my idea, and it might have been brought up here in the
past to the same sorts of screams of horror to which you refer later,
but I use the 'apply' pattern without too many internal objections
for this:

class Foo(object): # just a simple example, practically pointless _my_property = None @apply def my_property(): def get(self): return self._my_property def set(self, value): self._my_property = value return property(get, set)

IMHO, I find this easier to parse than either of your two examples.

Apologies if this has already been screamed at. :-)
