I believe the issues with opIndex and opSlice caused the bug. 
Now, those are fixed, and I guess it's safe to say that range 
interface is correct.

Although, I remember a discussion in the NG about somewhat 
"standardized" testing facilities for ranges ( 
http://forum.dlang.org/thread/20130321130858.00003ef4@unknown ). 
Precisely the semantic/runtime behavior, to supplement 
isSomeRange templates family. Do you, guys know, was there any 
activities on it?
