I am wanting to sort a list of tuples by the first and then the second item in the tuple. So [(1,2),(4,2),(2,5)] would become [(1,2),(2,5),(4,2)]  I am attempting to use the Sorty function but don&#39;t seem to be having much luck<br>
<br>tuplesort :: [(a,b)] -&gt; [(a,b)]<br>tuplesort [(_,_)] = sortBy (comparing fst)  -- this is an attempt to organise by the first element in the tuple<br><br>Any help would be much appreciated<br>
