Strictly speaking, I believe a critic is "a person who judges,
evaluates, or criticizes."  (
So, yeah, people suggesting improvements are critics.  I think we all
benefit from having good critics.  All sorts of changes have come as
the result of constructive critism -- packages, the threading module,
[].pop, {}.get, etc.  Probably lots more that I'm not thinking of.

I think the problem is that the people who have experience
implementing garbage collection are not the people who advocating
adding it to Python.  It's one thing to have used languages with
garbage collectors or to have read books and papers about them; it's
quite another thing to have done the implementation.  The gap between
theory and practice is greater in practice than in theory.

So go for it.  Many of us would love to look at some rough, but
running code.  Just make sure it is portable enough to run on all the
platforms that Python runs on, and make sure it has minimal impact on
C extension modules.  I doubt that it's impossible, but I expect that
it's hard.
