#5492: Underscore not a valid name for a class member
---------------------------------+------------------------------------------
Reporter: trinithis | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 7.0.4 | Keywords: underscore _
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
The following program is rejected:
{{{
class Foo a where
_ :: a
}}}
Note I could only reproduce when using a single underscore character.
Multiple underscores work fine. Mixing underscores with other identifier
characters works as well.
