Record fields not defined with pattern synonym in ghci
Another thing discovered while in the air: When you define pattern synonyms with record syntax, the fields aren't defined in GHCI:
$ ghci -ignore-dot-ghci -XPatternSynonyms
GHCi, version 8.1.20160419: http://www.haskell.org/ghc/ :? for help
Prelude> pattern Point {x, y} = (x, y)
Prelude> :t x
<interactive>:1:1: error: Variable not in scope: x
Prelude> Works fine when imported from a file.
