Why do we have enter_scope()
for functions but not for classes? A variable defined in a class body will not be visible outside (as a variable, will still be available as an attribute of course)

Yep, good point. Added enter and exit scope calls (with tests that were failing before)

Just in case, could you please add test for classes within functions and vice versa? Also maybe add a test where a variable is defined in a class and then is being red outside of class.

Added tests.
According to mypy_primer, this change has no effect on the checked open source code. 🤖🎉 |
Previously, we would ignore any class definitions and would fail to detect undefined classes and functions. This updates the logic to handle them.
Closes #686
