We could add a global mode, although that would prevent constant
propagation, if that's what you mean by adding them to the optimizer.
Or we could add variant functions like locale_strtolower() and
locale_strtoupper(). But I think I would want to hear from someone who
uses locale-dependence so I can understand what their needs are. I
guess the RFC will sort that out.
