That will allow easier and more efficient implementation, good!

ok.
Is it allowed to "normalize" subclasses of strings to regular string,
e.g. after:
class mystring(str): pass
class C: pass
x = C()
setattr(x, mystring('foo'), 42)
is it allowed that the dict of x contains a regular string 'foo'
instead of the mystring instance?
