Now that is interesting…

>perl -MO=Deparse -e "$a if $b %% 5 == 0"
$a if $b % %5 == 0;
-e syntax OK

So %5 is some sort of hash!?

From perlvar
Perl variable names may also be a sequence of digits or a single punctuation or control character. These names are all reserved for special uses by Perl; for example, the all-digits names are used to hold data captured by backreferences after a regular expression match.

So the scalar variant of those digit vars are well-known, but the hash variant is "reserved" and serves no special purpose by now.
