Good information.
To me, you're proposal above looks quite interesting. It also looks
to be a whole different thing than BOOST_STRONG_TYPEDEF, OPAQUE_TYPE.
And the paper above uses strong_typedef for something more akin
to you're proposal above.
It seems to be that this is a ripe subject to get sorted out and that
a boost library would be a good vehicle for doing this. your
OPAQUE_TYPE proposal would be part of this. We'd end
up with a couple of "things" which might or might not be
related.
