I really think we should separate the two things. The code we have today
doesn't change much to become C++. Making us reasonably happy across the
board is a 100,000 LOC review and refactor job. Starting a process of
continual review will be easier and more long term effective IMO. That
means refactoring an area of code before we add features, no more, no
less.

Ah - you are suggesting a 3.0 branch. I'm against this. Every time I've
seen a -major- change done outside of HEAD on a project, it suffers
badly. I'd like to see HEAD become C++, as a single series of commits.
Theres no need for a branch for that. (the rbcollins_cxxtest on sf could
be such a branch, although I've been using it to test the differences
that C++ allows us to make, as opposed to a straight syntax conversion.)

All our normal users. If we are happy that it is as good as 2.5S1 or
better, then we can release it.
