I filed an enhancement a while ago, that makes it completely feasible to  
have 0-impact forwarding from the new style operators to the existing  
operators. Supposedly it is included since Feb 2013, I haven't ever tested  
it.

Oh wait look, you were involved :)

I think a "useOldOperators" mixin template would be awesome to have for  
transitioning.
