There was a problem hiding this comment. This kind of check can easily pass by accident if there's typo or bytecodes change. Would be good to have a helper that asserts also that the thing not in is an actual uop id. There was a problem hiding this comment. It would. |

We could probably just get the version by doing
cls.type->tp_version_tag, right? Having both here just creates opportunities for them to be stale or out-of-sync, I think.There was a problem hiding this comment.

sym->cls.type->tp_version_tagis the version tag of the value's class now.sym->version.versionis the version tag it would have should execution reach this point in the code. Not quite the same thing.Uh oh!

I would imagine that a
sym->cls.versionthat's out-of-sync withsym->cls.type->tp_version_tagshould result in the bottom type, then, right? It's not possible in future code, since the cached tag is stale.
