Modern compilers produce almost the same binaries with such light
classes as they were fundamental types. But you're right about ABI.
This would surely affect mangling, for example.

Another solution is to add a wrapper that would be recognized by

int8_t n = lexical_cast< as_int< int8_t > >("127");

At least lexical_cast could encapsulate range checking during
