No. But in that case, I'm not sure it's good to use disable_if. According to
tests, lexical_cast is much more portable than enable_if/disable_if and you
don't need the generic lexical_cast<T>(T) case, only the string case.

I really wonder if somebody ever used lexical cast to convert between two
non-string types?
