There is a built-in function that works on any sequential collection. It could be used as follows given a List of symbols:
<lang>List('a, 'b, 'c).permutations foreach println</lang>
Output:
<pre>List('a, 'b, 'c)
List('a, 'c, 'b)
List('b, 'a, 'c)
List('b, 'c, 'a)
List('c, 'a, 'b)
List('c, 'b, 'a)</pre>
