Sorry, I misread what you wrote. I thought you suggested that an interned string can get "uninterned" somehow. Yes, sys.intern(x) will change x's status, but as you suggested, it can change x.__class__ as well. However, with a Symbol class in-place, I don't think there will be a need for such transitions. Even now, I don't see sys.intern() in user code too often.

Why can't we make interned strings a subclass of strings like bool is a subclass of int?
Because a string can change from being non-interned to
being interned at some point in its life.I did not know that. Can you show the code that would cause such a change?
