#7727: Nonsense evaluation: sequence [] = [] -------------------------------------+------------------------------------ Reporter: drb226 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: GHCi | Version: 7.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by monoidal): Dan: GHC behaves correctly here, if you ask for `sequence [] :: [[Int]]` you'll get `[[Int]]`. So it's an issue with documentation, which is easy to change. What would you like to see there? Is it enough to add that given expression `e`, GHC first attempts typechecking `it <- e; print it`, and if that fails `it <- e`, and if that fails, `let it = e`?
