[Python-Dev] PEP for Better Control of Nested Lexical Scopes

[Almann T. Goo]

Jeremy,

I definitely agree that option one is more in line with the semantics
in place within Python today.

I am not married to any particular keyword for sure--I would be happy
for the most part if the language was fixed regardless of the keyword
chosen.  "free" gives me the sense that I am de-allocating memory (my
C background talking), I don't think most people would get the
mathematical reference for "free".

I certainly hope that an initiative like this doesn't get stymied by
the lack of a good name for such a keyword.  Maybe something like
"outer"?

> I think free == global in the absence of other bindings.

I actually like this, would sort of make "global" obsolete (and thus
making the global scope behave like other lexical scopes with regard
to to re-binding, which is probably a good thing)
