At the moment, no. There has been a small push toward an OverloadedLists extension, which would allow you to use list syntax for anything that has a fromList (there would probably be an IsList class similar to the IsString class). I'm not sure where that has gone. I know there were several competing implementations.<div class="HOEnZb">

Hi,<br>
<br>
with [1,2] I can declare a list. Is there a similar notation for sets?<br>
Currently the only way I know is 'Set.fromList [1,2]' which is unhandy...<br>
<br>
