Let's not forget the Ton Hospel "high-precedence decrement"
operator ~- invented during a golf tournament (anyone remember
which one?).

IIRC, Ton's ~- invention allows you to eliminate the parens in:

    $y = ($x-1)*4;

by using instead:

    $y = ~-$x*4;

saving a whopping two strokes. This trick should work on any
twos complement machine -- and I'm not aware of any perl running
on any non twos complement machine.
