Yes, I've fixed this now.  Thanks.

I don't think so, because the result is not used directly in C++, but
it replaces the value in the expression where the "end" keyword
appears.  So in your example, for a(2:end) and a(2:4) to be
equivalent, the value returned from the __end__ function must be 4
(== numel(obj.x), I think), not 3.
