It looks to me like there are people who want a sort of ducktypeof operator.
arg1 ducktypeof MyClass Which would return true if the shape of arg1 where the same as MyClass. If I wanted to write as a refutable pattern I could end up with a large block that may be repeated in several class methods. It would be nice to shorten that so that you could declare tersely that your methods require a specific shape to be passed in.
