Yes by 'alias' I meant 'mask' and you clarified the python scope rules for
me.

At the moment shesdkin is a bit too restricted for my taste regards reusing
a local variable name as a different type.  By relegating a local variable
to the tempvars when it is reassigned at the same ident/parent as the
previous assignment i hope to broaden the python that shedakin accepts.

Well, the point of ShedSkin is to do what Python does, as much as
possible, so in this case, m is local to func, and this is therefore
an UnboundLocalError.

Maybe we understand "alias" differently.  In Python, this is a local
variable that *masks* the global.  It is completely different than the
global and can be freely assigned within func.

In general, I didn't follow your examples at all.  But I haven't
really used ShedSkin other than some hello-world-type stuff, so my
understanding of ShedSkin could just be insufficient.  I imagine
Fahrzin understood what you were saying.
