Yes, that would be nice. It would be incompatible with that idea, unfortunately.

The statement "def foo(...):" is just a shortcut for the assignment "foo=new.function(CODE, GLOBS, 'foo')". So why not make "def foo.bar(...):" a shortcut for "foo.bar=new.function(CODE, GLOBS, 'foo.bar')" ?

If the attributes of a property object are made assignable the following code will work:

prop = property()

def prop.fget(self): ...

def prop.fset(self, value): ...

This will also allow creating classes the way Barry suggested or creating new kinds of namespaces.

"Namespaces are one honking great idea -- let's do more of those!"-ly yours,
