Summary

Currently this will not be picked up by any implicit concatenation rule nor by formatting:

foobar = [
    "foo"
    # Implicit concatenation occurs even with comment
    "bar"
]

print(foobar)

Every other issue I could find on this appeared to be closed, but none of them seemed to handle the edge case of comments in between. So apologies if this is a duplicate but I couldn't find it.
