-So when calling `$myClass->processSomethingHeavy1(SomeModel::find(1))` the variable `$relation` will always have the same value as in `$myClass->processSomethingHeavy1(SomeModel::find(2))` as long as they have the same `foo_relation_id`. In spaties packge you would lose performance here, cause the ***containing method*** parameter ($someModel) has changed... Note that `processSomethingHeavy3` would also loose performance, even though the `foo_relation_id` would be the same, cause here also the changed **$someModel** would be used as the combination key.
