This is also a pet peeve of mine. Rebuilding STL w/r to all the thin we 
know how to do in a proper way now comapred to 198x.
Maybe some effort could be put on these.

What about saying that such containers can be walked using a set fo 
ranges, one per dimension and let then generate nested for loop for each 
range ?
