Huge 👍
A hook for cleaning up after ourselves would be useful but if destroy gets called at that point then that's fine.

Will there be a way to register expressions that don't have a - in their name? For example, ember-can's can, ember-cli-i18n's t, and ember-i18n v4.0's t.

Whats the reasoning behind requiring a - in the expression name?
As I understand its required for components to align with web components. Is it just to help differentiate between helpers and expressions?

[mixonic]

After discussion and consideration, I've decided to advocate for another direction. Instead of a wholly new type of template api, I'd like to introduce class-based helpers with a compute function having the same call signature as function helpers.

PR forthcoming, likely tomorrow morning at this point.

Regarding the dash- the new proposal will put the burden to change that requirement back on helpers themselves. With the glimmer refactor I think it is possible, will bring it up in discussion.
