I'll weigh in even though we're not asking me, since I'm more boost-users
than boost-dev,
but from your email alone, I'd choose failure-to-compile anytime. My
understanding of UB
is that it exists to give leeway to compiler writers for performance
reasons, and what you
describe doesn't seem performance related at all, so why choose UB? --DD
