I don't know anything about fold but in general a c++ array in the 
frontend is cv-qualified, not its elements.

I have been processing large source codes including STL, boost and 
custom code including function bodies and I have never seen a 
RANGE_EXPR. I suppose it's only used at later stages or only in other 
language's frontends.
