Edison 1.2rc2

[Robert Dockins]

Greetings!


The second release candidate for Edison 1.2 is now ready for  
comments.  The notable changes from RC1 are:

   * add strict variants of all folds and reduces
   * reverse argument orders to 'rcons' and 'lookup*' in
     Sequence
   * Add symbolic operators for lcons, rcons, append, and lookup
     from the Sequence API
   * Add symbolic operators for subsetEq, difference, intersection
     and union from the set API
   * rename 'single' to 'singleton' in all APIs
   * rename 'intersect' to 'intersection' in Collection and
     Associated Collection APIs
   * add 'adjustOrInsert' to the Associated Collection API
      (see http://www.haskell.org//pipermail/libraries/2006-February/ 
004952.html for a use case)


And the following are the remaining major issues I'd like to get  
feedback about:

-- Edison defines 'subset' and 'subsetEq' in the set API.  Data.Set  
has operations with the
    same meanings named 'isProperSubsetOf' and 'isSubsetOf'.  I am  
considering adoping the
    Data.Set names, but they are quite a bit longer.  Also what about  
the meaning of "subset"
    vs "proper subset"?  What do you find most intuitive?
-- Data.Map defines 'isSubmapOfBy' and 'isProperSubmapBy'.  Edison  
has no corresponding
    API methods.  Are they important enough to add?
-- What do you think about the symbolic operators?  Is the fact that  
(++) clashes with the Prelude a problem?
    Should the operators be folded into the "Data.Edison" module  
instead?
     (see http://www.eecs.tufts.edu/~rdocki01/docs/edison/Data-Edison- 
Sym.html)


In addition, I'm interested in any API related feedback you might have.
