Sounds good to me. I recently understood this and completely agree. Does 
this mean that all functions that can operate on different axes will have 
an "axis" keyword?

But these imposter functions should exactly the same signature as their 
shadowed brethren. (Just checking - wouldn't there be an "axis" keyword 
as per the question above?)
