Rename () into Unit, (,,...,,) into Tuple<n> (#21294)
This patch implements a part of GHC Proposal #475.
The key change is in GHC.Tuple.Prim:
- data () = ()
- data (a,b) = (a,b)
- data (a,b,c) = (a,b,c)
...
+ data Unit = ()
+ data Tuple2 a b = (a,b)
+ data Tuple3 a b c = (a,b,c)
...
And the rest of the patch makes sure that Unit and Tuple<n>
are pretty-printed as () and (,,...,,) in various contexts.
Updates the haddock submodule.
