Ticket #23 (new defect)
Opened 6 years ago
Case statement, pattern guard, comma indentation
|Reported by:||heatsink||Owned by:||Baughn|
|Version:||Keywords:||pattern guard, case, comma|
Commas in pattern guards inside case statements produce parse errors that prevent indentation. On the other hand, commas in pattern guards on function definitions don't cause the error. Using version 2.8.0.
-- Parse error after comma foo maybex maybey = case maybex of Just x | Just y <- maybey, y > 0 -> x + y -- No error after comma foo x maybey | Just y <- maybey, y > 0 = x + y
