FWIW `in` looks good to me, it's self explanatory , but `in.self` or `in.current` don't look god anymore. Would it be utterly insane to have `in.function` and `function.function` to reference to the function? If `in.function` works as `function.function` outside arrows, same as `in.count` reference to `function.count` outside arrows, then developers would probably always use the `in.function` version all the time and, when/if needed, have the ability to go `function.function`
I know latter sounds redundant, but it completes well with the `in` meta name I personally wouldn't mind.
