aihc-parser-1.0.0.2: test/Test/Fixtures/golden/pattern/paren-neg-literal.yaml

extensions: []
input: |
  (Con -5)
ast: |-
status: fail
reason: >
  Negative literals are lpat (not apat) per Haskell Report, so they
  cannot appear as constructor arguments without parentheses.
  GHC also rejects this: "Parse error in pattern: Con - 5".
