When you do, please try not to leave the Unicode question out of the
discussion. A separate name such as to_wstring seems insufficient to me because
there are times when you cannot know beforehand whether the string type you're
casting to is single-byte or Unicode (e.g. when writing generic code). I have
posted a plausible solution (using partial specialization on the contained
character type) before in

In fact, functionality for directly converting between ASCII and Unicode might
also be something that people would consider to be a "lexical cast." Perhaps
this is not something that everyone feels would be of use to the common
programmer, but to programmers working with international applications I think
it would. The standard already has half-hearted support for these people. Why
not aim for making it whole-hearted (certainly, that would take much more work
than just fiddling with lexical_cast, but it's a start...).
