Ok, I misunderstood what you were doing here.  I thought you were simply 
packaging AVL trees, but you're actually including the generic 
collections framework.

I'm not completely comfortable with shipping this framework with GHC at 
the moment, given the small amount of discussion it has received, and 
the volume of competition in this space.  This isn't a criticism of the 
design at all (indeed, I haven't looked at it in detail).  I'd much 
prefer to see this provided as a separate package for now.

Of course if a concensus emerges that this collections framework is the 
right way to go, then we'll certainly include it - a collections 
framework is pretty basic functionality.
