<3 Nice work.

This aligns with my gut feeling, which is why I voted Yes on the proposal to make this a hard error: it surfaces errors that already exist or, at least, forces developers to clarify their intent.

Great work! But instead of analyzing the top 1000 repos, which are rather high-quality I would guess, analyzing random repositories with the same amount of files/lines would reveal many more cases?
If your top 1000 repos have 1000000 PHP files, it would be nice to find random 1000000 PHP files on github, and analyze them. Maybe repos with at least 10 forks or 10 stars or simliar?
