There was a problem hiding this comment.
Kinda think return (ival !=-1 || !PyErr_Occurred()); is more readable - is there a reason we can't do this?

PR summary
Fix an inverted error-check in the pybind11 enum type caster in src/_enums.h. PyLong_AsLong signals failure by returning -1 and setting a Python exception. The correct way to check for failure should be: return !(ival == -1 && PyErr_Occurred());
Part of #31424
this is my first PR here; I just wanted to get the flow down of contributing here before making any larger changes :)
AI Disclosure
I used Claude Code to help understand the codebase. The fix itself is a one-character change I applied.
