Also happens rather rarely, in my impression, since you'd have to a) run
mbstring.func_overload which you can't remove and b) still need
non-overloaded string functions. And if you are in this rare situation,
it's usually better to have explicitly-named function, so that you know
what you are dealing with, not relying on subtle details of how names
are resolved vs. namespaces.
