Notwithstanding the above argument, can someone tell me why you can't just use && ... || in place of ?? ... !!, now that && and || propagate context to both sides? This is probably a failure of my imagination, but the only difference I've found so far is that && and || aren't lvaluable. Could they be made so? pugs> my $a = 42; (1 && $a) = 17; *** Can't modify constant item: VInt 42 pugs> my $b = 42; ($b || 0) = 17; *** Can't modify constant item: VInt 42 -- Peter Scott
