Beautiful. So who volunteers to put it somewhere appropriate?

Of course we could also use:

#define BOOST_STATIC_ASSERT_FALSE(x) \ BOOST_STATIC_ASSERT((mpl::apply<mpl::always<mpl::false_>, x>::value));

but that seems like overkill.

Hahahaha! If we have to resort to apply<>, we've definitely gone too far. Of course, someone will come up with a use case where apply<> should be used, and then I'll have to eat my words. :( Dave
