Very good :).

I've looked at boost::any in an updated boost repo (mine was an obsolete
boost-zero repo which has not been updated in a long time). The uses of
other features of type_traits has grown there, so more modularization
work would be needed.

Actually I thought that upgrading the compiler requirement would be such
a no-brainer as to require no further evidence of its usefulness than I
already presented. If that's not the case, then *shrug*.

If that's how boost works, then you're telling me :).
