Comment (by simonpj):

 I'm far from sure that it's a dup of #7495, so I'm reopening.  This ticket
 has a clear proposal; #7495 does not.

 By all means go ahead and forge a consensus about this ticket.

 I wonder if `IsList` could be a superclass of `AsList`?  That is, do you
 want to be able to pattern-match on a list-like thing, but not be able to
 use literals for that type?  Or are they best considered as orthogonal?

 The nomenclature clearly needs fixing!

 Simon
