Merge problems certainly increase the longer the developing code is
isolated from the trunk - whether or not you're using a branch for the
developing code. (When the project is big enough, that code skew is
inevitable - at least when using a branch you have the option to
occasionally merge form the trunk into the in-process branch. I didn't
follow the types/class unification very carefully, but have the impression
that you and tim did some of that - perhaps later in the process than you
would have, in retrospect, preferred.)
I'm not the CVS practices maven here - brian lloyd has that pleasure;-)
and in any case realize the cost/benefits balance is complicated. CVS
branching does offer some real advantages, but the complication of
realizing them can be an added burden, and CVS' foibles can muddy
cost/benefit balance a good bit, as well - so i don't mean to suggest
there's a clear-cut win here, one way or the other...
