The current implementation of mixin requires the target type to be the first argument:

IntegerMixin {
    Integer crazyPlus(Integer self, Integer other) { self - other }
}

This is ugly. We need to change it to support true mixins where we change the meaning of "this" to refer to the object:

IntegerMixin {
    Integer crazyPlus(Integer other) { this - other }
}

You should also be allowed to store state in the IntegerMixin class so that mixins can be stateful
