My implementation essentially does this as well. However, I
have devised a metaclass (called ClassObj) that does not actually
replace the class with an instance. Instead, each class keeps a reference
to singleton instance. All attributes are stored on the class object, but
methods are forwarded to the instance (since Python won't allow you
to call methods on a class). The advantage of this is that the classes
can even be subclassed. This metaclass largely eliminates the
distinction between classes and objects; a ClassObj can effectively
function as either.

I'm definitely interested. I have put my work-in-progress code up
if you want to look at it. It is at http://www.brenbarn.net/misc/gui/
(You may have to change the import statements in the files slightly; I
haven't bothered to make sure the directory structure there is the same
as on my local system.) This is obviously incomplete, but it gives an
idea of the kind of thing I am doing. Let me know what you think!
