While we're here, I think perl should understand ordinals (http://mathworld.wolfram.com/OrdinalNumber.html), too. The syntax is quite ready for it: $w = +0...; $w1 = $w + 1; assert($w1 > $w); sub wn($n) { $n ?? wn($n-1)+1 :: $w } $w2 = 0... + wnÂ0...; assert($w2 == $w*2); Just think of the possibilities! :-) Seriously though, putting 1st, 2nd, nth, etc. in the language is somehow very appealing. It makes my heartburn about m:1st// settle down quite a bit, too. Luke
