Summary

Sort of a followup/variation of #2039 that I found while messing around, since #2039 was fixed but this wasn't.

If a function takes exactly itself as a parameter, you get a stack overflow:

from ty_extensions import TypeOf
def foo(x: TypeOf[foo]):
    ...

Though since as far as I can tell this requires TypeOf it may not be worth worrying about.

Also playground link from #2039 (comment) to show the playground is updated and to get your playground unstuck from the crash loop if you used the example link:
