I think this will be a breaking change for @lastmjs, so I'm pinging to make sure this works for them.

I'll test this later today, since I was having the mentioned issue.

[lastmjs]

I'll see if I can test this soon

I'm getting the following test error with this branch:

It works now! Let's wait for @lastmjs confirmation, and we can merge it :)
