Ahh... not to be such a thorn in your paw, Michele, but what about the
following (6-line :-)) class:

class RecognizeStatic_Traditional:
    def __init__(self):
        from inspect import isfunction
        for k,v in self.__class__.__dict__.items():
            if k.startswith('static_') and isfunction(v):
                self.__class__.__dict__[k[7:]] = staticmethod(v)


Now of course, if your 'C(RecognizeStatic_Traditional)' class decides to
have an '.__init__()' method, you'll need to call the parent's init.
You could also call the parent method something like
'.methods2static()', and call it explicitly when you wanted that to
happen.

But this is my ongoing challenge to have someone show me what
metaclasses are *really* doing, other than changing spelling a bit.
Mind you, I'm sure I'll see it in time (since the Martellibot thinks
there is something to see).

Yours, Lulu...
