Comment (by simonpj):

 I like comment:11.

 Do start a wiki page to describe the design.  Issues you don't cover yet
  * Pattern matching
  * What about `[a,b..c]` and friends?
  * One could add this as a different and incompatible extension to the
 existing `OverloadedLists`, but it would be better to get the best of both
 worlds.  Can we?  What can the existing `OverloadedLists` do that the new
 design cannot?

 There are probably more issues.  A wiki page is a good place to put the
 current best-effort design; while the ticket is a good place to discuss
 it.

 Simon
