#4176: reject unary minus in infix left hand side function bindings that resolve
differently as expressions

Type: bug | Status: new

Component: Compiler | Version: 7.2.1
Resolution: | Keywords: fixity resolution
Testcase: | Blockedby:
Difficulty: | Os: Unknown/Multiple
Blocking: | Architecture: Unknown/Multiple
Failure: None/Unknown |

Comment(by maeder):
I agree it requires extra code for patterns, but considering that a
missing fixity defaults to 9 (the highest) it would even make sense to
always require parens around "- (integer | float)" to the left of infix
ops. But I suppose there are not many patterns like:
{{{
-1 `op` ...
}}}
