What he did also say is he wanted the equivalent of C++'s "at", 
which is the equivalent of "checked random-access" (or "checked 
dictionary access").

So the actual requirements aren't very clear. In terms of "C++ 
at" equivalent, I don't think we have anything equivalent to 
offer. That said, I've never seen anyone use "at" in C++ ever. 
I'd assume it's more of a java/C# thing to do checked accesses?
