loader.js implementation feedback

Answer 1 · 2015-12-23T22:51:24.000Z

resolution: it could be a factory for back-compat with dynamic module systems.

action: it should test for callable or module registry, and act accordingly.

Answer 2 · 2016-01-25T22:07:12.000Z

solves as part of refactor #122

Answer 3 · 2016-01-25T22:50:55.000Z

Does this mean returning a factory in instantiate is no longer supported?

Answer 4 · 2016-01-25T23:08:18.000Z

It is supported. Step 4 allows optionalInstance to be callable, then in https://whatwg.github.io/loader/#ensure-linked we guarantee that the factory is executed, and that it returns a namespace exotic object.

Will read more carefully next time. Thanks for clarifying!
