True. While there's the general '"ab"+"cd" is (not) "abcd"' caveat, I'm
sure quite a bit of code out there assumes that parsed identifiers in a
module, such as the names of functions and classes, are interned, since
this was often communicated. And in fact, explicitly interning the same
name might return a different string object with this change than what's in
the module/class dict.
