Well, you know that the unqualified name is "map", i.e. also for 
Data.Map it's not mapMap or mapFM but <YourChoice>.map.

I think, that was discussed when including Data.Set and Data.Map (but 
only isEmpty became null). Replacing the import of Set by List does not 
work well, but Data.Set could be easily replaced by a different Set 
implementation with the same (or a similar enough) interface.
