Explicitly marking an argument as an `in` argument has effect on overload resolution and needs to be known to the dynamic binder to be able to make appropriate decisions. For the time being there is not way to pass this additional information.
That would require a small expansion of APIs used by `dynamic`. When we have such API, we should predicate this scenario on the presence of such API.

For now, In order to not perpetuate accidental and likely incorrect behavior we should block this scenario.
