Allow record wildcards with pattern synonyms which are defined in GHCi
With pattern synonym pattern Point {x, y} = (x, y)
we can write
>>> let { x = 1; y = 2 } in Point { x = x, y = y }
(1, 2)
>>> let { x = 1; y = 2 } in Point { x, y }
(1, 2)
but record wildcards ain't workin
>>> let { x = 1; y = 2 } in Point {..}
<interactive>:342:25-36: error:
