I've been preexposed to the Ocaml syntax, so I think '|' looks nicer. I even 
format cascading uses of the ternary operation the same way:

  x = cond1? result1
     :cond2? result2
     :cond3? result3
     :/*default/* default_result;

I fully expect it to conflict, unfortunately, and the switch-on-type should 
probably use something like tswitch/tcase.
