Good, so I propose to create a separate package (collections?) where
we'll put the AVL-tree based collection types, plus the code they are
I will do this next week, provided I have the rights to create a new
package on darcs.haskell.org
Later on Data.Set/Map/IntSet/IntMap shall be moved to that package.
