I discussed that briefly on Slack with a couple other

My understanding is the `rt` is the language implementation
and `core` is the low level library for users.
The code in `rt/array` are language implementations. They are
not to be imported by the user. They are, however, required by
the language to implement D's built-in arrays, so that is why
they are publicly imported in object.d.
I think that fits core.internal better than rt. Have you
considered that during said discussion?
