I think we'd better leave this for @pkofod's judgment tomorrow. Thanks!

I'm going to go ahead and merge it. I'll flag it so we can follow up and fix the last E712 errors once we hear back from Patrick.

[llorracc]

OK, sounds good.

Thanks! Wrt the other things, I'd have to check first that it works with numpy arrays.
