The future of the haskell2010/haskell98 packages - AKA Trac #9590

[Austin Seipp]

Hi Ryan,

Yes, that or one of the various superclass instance proposals would
probably solve this without too much grief, since we could simply
export Applicative, then automatically get an instance for it
afterwords at no cost.

This was very very briefly discussed yesterday, but I left it out of
the 'Possibilities' list here because it is simply contingent on too
much work, and too much discussion, in too short a span of time. There
have probably been a dozen proposals for this kind of functionality,
and I don't think any of them ever even got to the implementation
stage.

Unless someone has a hidden, ready-to-go patch with these features and
it'll be committed very very soon (which I unfortunately doubt), I
just don't think it's realistic to consider these approaches as
solutions right now.
