For the most part keeping new code compatible with both Python 2.6 and
3.1 isn't a challenge, the most noticeable issue is with string data.
The obvious downside is if the code has to run on an interp that
doesn't understand the modern 'except ClassName as varname:' thing.

In my experience (FreeBSD), compiling vim with Python, Perl, or Ruby
support (etc), generally requires recompiling vim after upgrading the
corresponding language.
Note also that (if like me) you manage vim installations `by hand` on
all systems, rather then use the systems package management syst

If it's such a big hairy deal, just recompile a copy of the C Pre

For me a language is a language for the most part, doesn't matter...
Python is a language I choose for any of several reasons:

Windows

2.) Working in Pyt

It's most valuable for sending data to an existing instance of vim, by
name. Both files and keystrokes can be sent fwiw.
vim basically organizes it self into buffers,
to
speed things up and save on wrist strain. Before I read a tutorial
