After PEP 701, having comments mixed with debug expressions is possible but the interactions has not been discussed. For instance, consider this code:

a = 1
f"{a = # my comment
}"

this produces:

'a = # my comment\n1'

which is surprising. What we should do here? I think we should probably not include the comment but we should agree on the behavior before a PR can be made
