That's not a "do once", that's a "test true once". So you'd want something more like a flipflop operator: 
    next if ($_ eq 'foo') ff False;

Presumably the compiler can recognize that the False test will never be true.

Those parens bother me though. Maybe the flipflop should be of looser precedence...say, the same precedence as ??!! perhaps... Hmm...
