Had time to think about this on the drive home.
I've eliminated the for loop which was my goal.
Any "better" or "cleaner" way of doing this, I'm all ears. ;)
die Some::Exception.new.throw
if %!panels.elems && !%!panels.values.map({
$end_y < .start_y || $start_x > .end_x ||
$start_y > .end_y || $end_x < .start_x
}).so;
