Pattern: Explicit call to minus()
Issue: -
This rule detects when the minus(Object) method is called directly in code instead of using the - operator. A groovier way to express this: a.minus(b) is this: a - b. This rule can be configured to ignore minus.xor(Object) using the ignoreThisReference property. It defaults to false, so even minus(x) will trigger a violation.
This rule also ignores all calls to super.minus(Object).
