Investigating this I find out that the form that function_types
generates, which is what BOOST_TTI_HAS_MEMBER_FUNCTION uses, is:
std::vector<int>::const_iterator (std::vector<int>::* )() const
does indeed work.
It does seem as if putting the 'const' at the end is the correct
signature whereas putting it where you originally had it suggests a
const member function pointer and not a member function pointer to a
const member function.

All the more reason to use the mpl sequence form rather than the
composite form unless there is really a need for the composite form with
some sort of arcane calling convention or compiler-specific syntax.
That's just my opinion of course and I am glad to supply both forms.
