Thanks!

Also another thing, I don't remember if the docs explain the library
behavior with cv-qualified member functions-- I should probably go back and
read the docs instead of just asking you :) I did test cv-qualified member
function introspection and it seems to be working fine (as it should). If
it's not documented, can you please document it? The same would apply to
cv-qualified member data (which I didn't test).

For example:

struct C {
    void f () const {}
    void g () const volatile {}
};

BOOST_TTI_HAS_COMP_MEMBER_FUNCTION_TRAIT(has_f, f)

has_f< void (C::*)() >::value // 0
has_f< void (C::*)() const >::value // 1
has_f< void (C::*)() volatile >::value // 0
has_f< void (C::*)() const volatile >::value // 0

BOOST_TTI_HAS_MEMBER_FUNCTION_TRAIT(has_g, g)

has_g< C, void >::value // 0
has_g< C const, void >::value // 0
has_g< C volatile, void >::value // 0
has_g< C const volatile, void >::value // 1

Thanks.
