Sure, but that argument cuts both ways. That is, it's cheap enough for the constructor, but it's also cheap enough for the `size` function depending on the application.

You need strlen for more than size(). It's also needed in end(), operator[], at(), remove_prefix, substr (both overloads), the find functions taking a start offset, back(), actually everything taking a start offset, ends_with, and probably others as well.
