It's like the operators: we either have different switch() for strings
 and integers or we have typed variables. Without this restrictions one
 cannot optimize (IMO we should have both since that would allow for
 much better type checking at startup -> a lot of possible script errors
 can be easily indentified => more user friendly).

How about using match() for sswitch()?
Also should we use only strings or REs too, e.g.:

match($v){
    case "foo":
    case /[0-9]+/:
    ...
}
