#3013: New simple GADT feature

-----------------------------+----------------------------------------------
It's somewhat of an anomaly that the following does not work:
{{{
data T where
Foo, Bar :: Int -> T
}}}
Since the comma syntax works for type signatures and records it would be
natural for it to work with GADTs.
