You might find the following function useful, which I
developed for use in PyGUI.

This did get out, but I can't answer except to suggest looking at code for
other C extension modules. Nested (inner)
Hello,
I asked this question some time ago, but as I got no answer, so I just
try it a second
time.
I am working on a C extension module that implements a bunch of
classes. Everything
works fine so far, but I cannot find any way to implement class
attributes or inner
classes. Consider you have

Perhaps you want to roll your own VirtualProperty descriptor? Here's
one based off the property implementation

I think you may find Alex Martelli's PyCon slides somewhere
on the net. The black magic slides discuss this issue. But I
think the fix he suggests is not dissimilar from what you
are already doing. I don't remember exactly now, but
it is always worth a look.

I did put comments above each property line - so one might argue that's
about the same effort as writing the method explicit. Alternativ
I'm not aware of possibility that works as you first expected. You yourself
explained why.
But _maybe_ you can use lambda here - that creates the layer of indirection
one needs.
foo = property(lambda self: self.get_foo(), lamda self,v: self.set_foo(v))

My problem is about properties and the virtuality of the methods. I
would like to create a property whose get and set methods
are virtual. I had the same problems in Delphi before and the solution
was the same. I created a private _get method and a public
get method. The former one will call the
