[ Pending RFC ] create Cell

[NullVoxPopuli]

RFC: emberjs/rfcs#1071

I want to RFC Resources, but we don't really have an implemented way to have reactivity in them right now.

We have:

• trackedData in @glimmer/validator -- this whole package should not be used by ember users tho, and most of its exports are not-RFC'd and should be considered private API
• @glimmer/tracking/primitives/storage -- this would work as an implementation of "Cell", but isn't implemented yet
• @tracked - requires creating class state, which many would feel is too cumbersome / verbose when for the "simple" cases, like having one value

Tho, now that I've implemented this, I wonder if it can be placed in @glimmer/tracking, since @glimmer/validator exports so much.

Would it be worth making the set a bounded func? For example:

  set = (value: Value) =>  boolean {

This way we could pass this into templates and not need to create a func just to set the value of a cell.

how do you mean?

it's a bug in the vm that this doesn't work:

<button {{on 'click' (fn cell.set 'hi')}}></button>
