You can usually use map instead of foreach:

List("a","b","c") foreach println

can be replaced with

List("a","b","c") map println

except for the return type, which you aren't interested in anyway when using foreach.

The only difference is the return type (Unit vs List[Unit]), which you aren't interested in anyway when using foreach.
