#4176: reject unary minus in infix left hand side function bindings that resolve
differently as expressions
---------------------------------+------------------------------------------
Reporter: maeder | Owner:
Type: proposal | Status: new
Priority: normal | Component: Compiler
Version: 6.12.3 | Keywords: fixity resolution
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
a program like:
{{{
infix 7 ##
(##) :: Int -> Int -> Int
- 1 ## 0 = 0
_ ## _ = 1
}}}
evaluates (unexpectedly) as
{{{
*Main> - 1 ## 0
-1
}}}
