As I import just Data.Set there is only one fromList in scope. It has
type (Ord a) => [a] -> Set a so there is no ambiguity.

I should have used toAscList to get a sorted list. toList gives no
guarantee of the order of the resulting list but in actual fact, if
you peek at the source code, they are the same function so I got away
with it.
