I've seen far too many maintenance programmers who just start madly trying 
anything when they get a compile error.  I can see them dropping "::type", 
and then assuming all is well because the compiler becomes silent.

I tried for years never to use macros, but have given up for test and other 
error detect needs like BOOST_STATIC_ASSERT.  They allow you to wrap 
messiness in ways not so subject to misuse.

I know that isn't politically correct, but it seems to be reality.
