another interesting feature may be ruby-style matching defined by execution of special function `match` instead of pattern matching:

switch var of 1+1 -> print "var==2" [5..10] -> print "var in [5..10]" (>20) -> print "var>20"

where (var `match` (1+1)), (var `match` [5..10]), (var `match` (>20)) is tested

With view patterns you can write case var of ((== 1+1) -> True) -> print "var==2" ((`elem` [5..10]) -> True) -> print "var in [5..10]" ((> 20) -> True) -> print "var>20" Or you can just use guards, of course. Twan
