one thing i try to have for the "switch" entry, is that the val only
appears once (syntactically).

this would be better in if_then_else where i give the n-ary
if_then_else. The problem is I don't know if it would better with a
comment telling the conditions must be separate, or writing explictly
the cut

i'd prefer an anonymous solution. is there one?
