Scala: good way to keep pairs of strings

Question

What is a neat way to hold pairs of strings which are not necessarily key-values (might have duplicate keys), for a small collection? List[List[String]] works obviously but looks dirty.

Answer 1

List[(String,String)] is the standard solution:

scala> List(("foo","bar"), ("foo","baz"))
res1: List[(java.lang.String, java.lang.String)] = List((foo,bar), (foo,baz))

Answer 2

Tuples are the ideal data structure to represent pairs.

So use a list of (String, String) tuples.
