This has a readability issue, though: you've buried the lede. The condition
should be up front where it stands out, not hidden at the back. The wide
usage of the Perl 5 "or" convention actually derives from this: both the
prefix-or and postfix-unless were faster than the explicit if, but
prefix-or vs. postfix-unless was judged to be cognitively a speed bump vs.
a brick wall.
