I think it should be straightforward for the OP to write a rot13
transformation and apply that (at compile-time) to the mpl::string (or
even vector_c<char,...>.) Then he can use the inverse + your function to
compute the deciphered string at runtime every time he needs it. Though
I guess he could also have the computation of the inverse set up at
compile time, just not execute it.
Interesting mental exercise anyway!
