Answer 1

Having only two possible value types as in your example would allow to use the Either type with the sub-types Left and Right:

val m = Map("words" -> Left("one two"), "rows"-> Right(23), "cols"-> Right(45))

If you get back a value from the map, you can check what you have, e.g. with pattern matching or using isLeft and isRight, and "unwrap" it accordingly.
