$foo = $bar:$nuu;    # Currently meaningless

I really don't want to have to try and parse

$concated = $x < $y ? $x:$y : $y:$x;

I think the ' _ ' operator is ugly, but not that bad. In general I don't think there will be much call for it in the future since we will be able to say things like

$string = "for $x + $y the answer is $($x+$y)\n";

instead of

$string = "for $x + $y the answer is " . ($x+$y) . "\n";
