> The lowest impact fix from a code change would be to add a type equivalence check for constants as Raymond first suggested, as that only involves adding an extra check to code_richcompare: https://hg.python.org/cpython/file/tip/Objects/codeobject.c#l416

It is not so easy. (1,) and (1.0,) are equal and have the same type. To make correct type-sensitive equivalence check, you need to introduce new protocol, new special method on low level and new operator/function on high level.
