• What are you trying to do? I have this code:

  
  type My struct {
  x     *int
  }

func (my My) cmp(other My) bool { return (my.x == nil && other.x != nil) || (my.x != nil && other.x == nil) }

- What would you expect to happen?
No refactoring tips or a simple tip to remove brackets.

- What happens?
Intellij proposes automatic refactoring to:
```go
func (my *My) cmp(other *My) bool {
    return my.x != nil && other.x == nil
}

This suggestion also pops up for all other similar boolean cases.
