Give it a chance to sink in.  It's a good idea even if you ignore
export because it reduces the chance that a template's meaning will
change based on definitions that follow it, allows syntax checking
before instantiation, and adds rigor.

I wouldn't count on it.  CW 7.x couldn't handle the "sizeof() trick",
so *lots* of basic TMP things (like is_convertible) fail there.  Of
course, maybe you're sure that none of these things are used...?
