This paper http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2141.html explain its relation to Opaque types.
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. Robert Ramey
