Request for references on interface inheritance 
Hi! Am I glad that you left information in interface inheritance on your talk page; I was trying to remember who helped clarify the stub (even though your last reply was posted more than a year ago!) The "What links here" was very helpful in this regard.

A pair of  challenges have been made against the stub; do you know of any good reference material to address the challenges?

Also, in your previous reply, you had mentioned the need for concrete examples; do you know of any reputable sources for such information? Cheers, Folajimi (leave a note)
