It is planned for interfaces to be able to contain template member  
functions, those functions would not be virtual or overridable, and would  
need to be expressed completely in terms of the interface.

They are like final interface functions.

I assumed this was already done, as it was a mitigating factor when  
fleshing out the new operator design that you could simulate previous  
behavior by creating a virtual function that then was called by your  
template operator function.
