Perhaps is there was a specialization for lexical_cast<int8_t> and/or
lexical_cast<char> which implemented the "correct" behavior as the
semantics for lexical_cast suggest (not an expert with cross platform
types, but I'm guessing 'short int' will always be 8 bits, unless I'm
missing something), maybe this will "just work"?
I tried looking at the code which involves lexical_cast, but I'm
seeing too much BOOST_PP_* stuff that I currently don't have the
Any pointers on how to make that happen? Or would leaving it alone and
saying in the docs that this isn't going to happen correctly be
