If you named your variables properly and your editor supported type hints, you'd have none of these issues: I used generic names for demonstration.

Compare it to

  family_adults = [ person for person in family_members if person.age >= 18 ]

Code should be as readable as possible by default: I'd argue you do not even need types in code with good naming, though they do prove their worth in codebases being evolved for a long time and many people.
