| // The correct implementation of `Equatable` (and `Comparable`) can be tricky for class | |
| // hierarchies. To make it easier, it is better to follow a well-defined pattern. Here | |
| // is my suggestion on how to do it: | |
| // 1. Define a protocol for polymorphic test function for equality (or comparison): | |
| // Note: operators are not polymorphic (not virtual in C++ terms)). The function to | |
| // call is determined and hard-coded at compile time. | |
| /// A protocol to ammend `Equatable` for use with `class` types. |

Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…
