Original issue's description:
> [runtime] Initial step towards switching Execution::Call to callable.
>
> Currently Execution::Call (and friends) still duplicate a lot of the
> Call sequence logic that should be encapsulated in the Call and
> CallFunction builtins. So the plan now is to switch Execution::Call
> to accept any Callable and just pass that through to the Call builtin.
