I see. The basic lexical_cast should be clean and easy and I don't
like making it too complex. Also, I'd like to see lexical_cast in the
public release of the boost library rather sooner than later and I
definitely don't want to be the one who defers the release. Speed
could be added later - but the functionality is IMHO more important
now. Please don't care too much about my performance problem... there
are a lot of things I can do to speed up my program that do not depend
on the implementation of lexical_cast.
