Very interesting. Not just the way you generate code, but also the way
you pass string literals to metafunctions. Your variadic template +
std::make_index_sequence trick seems to be able to replace the macro
magic for compile-time string construction. It looks like
BOOST_<whatever we end up with>_STRING could be improved with that (I'll
have to check).

Note that you should be able to "store" the length of the string in what
CTTE_WRAP_STRING constructs (you can get the length with sizeof or with
"pattern matching" on the char array length) and then you can also deal
with the corner case when a string literal contains \0 characters.
