Metaclass abuse? Oh, I'm sorry, I thought that the point of metaclasses were to offer a way to make "magic" happen in a somewhat pragmatic manner, you know, through metaprogramming. I would call this particular use a practical application of standard Python semantics.

I'd say using a class statement to define a property is metaclass
abuse, as would anything that wouldn't define something class-like. The same is true
for other constructs, using an decorator to define something that is not a
callable would IMHO also be abuse.

That said, I really have an opinion on the 'create' statement
proposal yet. It does seem to have a very limited field of use. I'm quite happy with
using property as it is, property('get_foo', 'set_foo') would take away most if not
all of the remaining problems.
