What is that, Vue?

If that’s horror to you, you’ve been sheltered. That’s quite readable, though I’d make the long lines into their own subroutines.

Why not factor out the ! via de Morgan’s laws (which would also remove most of the parentheses, as iirc && binds tighter than ||)? Also, does that language have a {#continue} sort of syntax for loops? If so, you could make it a guard clause.

Delightfully devilish, indeed. You made it as easy to read as possible though.
