list literal gotcha and suggestion

[Reinier Zwitserloot]

Scanning my codebase, they are quite rare. As the set literals are  
causing rather a lot of pain, let's see some proof before going too  
far down this road.

Pain caused by set literals:

  - ambiguity of {} - is that the empty set or the empty map?
  - set/list confusion.
  - the parser becomes quite a bit more complicated to handle the  
difference between sets and maps.
