Yeah, that's us.

MPL vectors can hold characters, e.g.:

typedef
mpl::vector_c<char,'h','e','l','l','o','w','o','r','l','d'>
pseudo_string_literal_0;

Then you can nest MPL vectors, like this:

typedef mpl::vector< pseudo_string_literal_0, ... >
pseudo_string_vector;

Then write an STL UnaryFunction to output the
characters of each pseudo_string_literal.  Finally,
put it all together with mpl::for_each<>.

Sorry, I have time only to give you this brief
outline.  (I'm busy trying to implement some advanced
numeric metafunctions, compile-time rationals, etc.)
