Replying to [comment:3 simonpj]:
> I really, really want to make operators into type '''constructors'''
rather than (as at present) type '''variables'''. So that we can write a
type `(a + b)` rather than `(a :+ b)`. See
http://hackage.haskell.org/trac/haskell-prime/wiki/InfixTypeConstructors.
Doing this is, I think, straightforward, but it still needs doing.
Really nice. What GHC version can be expected to have this feature? I’d
like to use it.
