Console errors after updating from 1.0.3 -> 1.0.5

in my app, updating ember-classic-decorator from 1.0.3 -> 1.0.5 as the only change throws console errors and breaks the app when running in dev mode

This should be fixed in the latest release, please reopen if it is not.

Ah, also you may need to update ember-decorators-polyfill, this bug was caused by interactions between these two addons.
