Looks good to me now !

We should decide first whether we have a proper naming for all this operation query methods and then get them in consistently.

Committed b5411b1 and pushed to 8.x. Thanks!

If this is a public API call, then opFoo has zero meaning. Maybe addFoo is wrong but something has to be better than opFoo. Do we mean operation, opportunity, opening post? At least spell it out.

I guess we can iron out the details about naming after massing conversion.
