Benchmarked, no statistically significant change in performance when used in classic class syntax! I think this is ready for review 🎉 |

Followup: We should flatten this class into Component so we don't need to use this decorator

This PR refactors the Descriptor system in Ember metal, mostly replacing it with a Decorator system instead. `defineProperty` has been updated to apply decorators following the currently implemented spec. This means that the value returned by `computed` goes through the exact same flow when applied as a decorator using decorator syntax, and applied using classic syntax.

Was this change intentional? Shouldn't it be ...args instead?

This PR refactors the Descriptor system in Ember metal, mostly replacing

definePropertyhas been updated toapply decorators following the currently implemented spec. This means

classic syntax.
I was considering pulling out the ComputedDecorator stuff into a separate
package, it's relatively isolated from the rest of
metalat this pointso it would make some sense. Thoughts?
