Matthias Urlichs added the comment: Ah. Thank you for pointing me to that feature, I completely missed it. The proposed enhancement thus boils down to "implement a couple of pdb commands to display and modify this skip list". I'm +1 on keeping the default empty. When

[issue32900] Teach pdb to step through asyncio et al.

New submission from Matthias Urlichs : The attached patch is a proof-of-concept implementation of a way to teach pdb to "single-step" through non-interesting code that you can't skip with "n". The prime example for this is asyncio, trio et al., though decorators like
