As a note, currently, I would need at least the reraise and exec_ functions from six;
Fwiw, reraise is fairly trivial and wouldn't be a big thing to carry in Twisted.
exec(code, [globals, [locals]]) works on both Python 2 and Python 3, and seem to have similar behaviour, so I'm not sure why exec_ is needed. Indeed, test_exec_() from the six source passes using the builtin exec in place of six.exec_. Ah, I've tried only with Python 2.6 and 2.7; perhaps there are differences on earlier 2.x versions?
Actually, Twisted now only supports 2.6 and 2.7 anyway, the issue is that the old syntax "exec code in globs, locs" is a SyntaxError in Python 3. In any case, in light of the discussions (and especially Jonathan's repost of Glyph's opinion), I'll opt for copying the required code to our twisted.python.compat module (copying the whole of six is not really practical, particularly because we'd still need additional compatibility modules). Thanks all for giving your input.
