[issue39215] Type Annotation of nested function with positional only arguments triggers SystemError

[Anthony Sottile]

Anthony Sottile <asottile at umich.edu> added the comment:

Looks as though annotations are using `LOAD_NAME` when they should probably use `LOAD_GLOBAL`?

```
$ diff -u <(python3.9 -m dis t2.py | sed 's/0x[a-f0-9]*/0xdeadbeef/g;s/t2\.py/FILENAME/g') <(python3.9 -m dis t3.py | sed 's/0x[a-f0-9]*/0xdeadbeef/g;s/t3\.py/FILENAME/g')

t3.py is the same as t2.py but without positional-only arguments
