My contribution to the discussion is that I don't think supporting C++
language subsets is worth complicating the interface in the way you
propose.  Maybe lexical_cast<T*>(whatever) should return 0 on failure
and that should be enough for those who can't handle the exceptions we
want to throw... though I don't know how (or if) that interacts with
things like char const*.
