FULL DISCUSSION
 

To people wondering why this syntax persisted so long: the bug produced by this syntax was actually the only way to have state variables, before the keyword state was introduced. This is why the bug was not fixed. Some people actually used it as a short syntax to implement a state variable:

$ perl -E 'sub flip_flop { my $t if 0; $t = !$t; say $t ? "flip" : "flop"} flip_flop() for 1..4'
flip
flop
flip
flop
