TYPE_CHECKING block scan bug

[Dliwk]

Problem Description

Error while generating documentation for annotated variable in module with TYPE_CHECKING block.

pdoc does it standard stuff from #293, but modifies content of self.obj.__dict__ (i.e. adding there things imported from TYPE_CHECKING block) while being within loop and after that hit RuntimeError: dictionary changed size during iteration.

Steps to reproduce the behavior:

1. https://gist.github.com/Dliwk/81dfaa01e79f8042e477a6f1769e6a45
2. pdoc module

System Information

pdoc: 10.0.0 (+1, commit eb686bc)
Python: 3.10.2
Platform: Linux-5.16.5-arch1-1-x86_64-with-glibc2.33

Perhaps we just need to execute code in these blocks right after importing them (and before entering this loop). 🤔

Thanks for the great repro - fixed!

Fun to see how the existing test case for TYPE_CHECKING did almost the same, but missed it by an inch (diff). 😅
