@ef4 does this need to be in a macroCondition somehow? (exports have to be top-level don't they?) since pre ember-source-4.1, this cached export doesn't exist?

I think you can write this in a way that isn't a SyntaxError even when cached is not exported by ember metal:

import * as metal from "@ember/-internals/metal";
const { cached, createCache, getValue, isConst } = metal;
export { cached, createCache, getValue, isConst };

It means our module always exports the name cached, but on older ember its value will be undefined.

will that work pre 3.27? I know some modules weren't allowing import *
I mean, I guess I'll find out!
