I think its the cleanest way of implementing all that string mess. Want
some {byte, code point, grapheme} string length: call
string->str_vtable->length. Want to SHR an Unicode string, the vtable
throws an exception. The question is: which of all these vtables depend
on the string and which are "environment" things. If there are a
reaonable amount of the former, a vtable is the way to go IMHO.
And there are or course some binary ops like concat but not much.
