wait(,) of current-window.

Bugs reported in Proparse sometimes lead me to come up with some pretty funny looking but legal code. The following script displays a couple of strings and then waits for keypress of '(' or ')'.

function wait returns character:
  display "in wait()".
  return "".
end function.

display "hi".
wait().
wait(,) of current-window.

What fun. :)
