returner() doesn't record method calls

A method created with returns= records its calls: >>> d = Dingus(x__returns=5) >>> d.x() 5 >>> d.calls [('x', (), {}, 5)] but a method created with returner() doesn't: >>> d = Dingus(x=returner(5)) >>> d.x() 5 >>> d.calls []

I want to deprecate "returner"; it's confusing anyway.
