Thanks for the suggestion, Chris, but I guess I was thinking more of
"backwards compatibility" issues.  This comes up currently for me
because I am writing a CGI app, and version 1.5.2 of Python still seems
to be installed on web servers (because, until recently, at least, it
appeared in most Linux distributions.)

For that reason, for example, it would be nice to  be able to
automatically know that something developed using Python 2.1 was free of
string methods so it would run on 1.5.2.  (Even better would be a
"backwards-version source-code translator"--that is, something besides
my tired brain and aching fingers <wink>.)
