Yup.  About the only potentially weird thing there is that, assuming C++ 
  style iterators, it would require reverse iterators and forward 
iterators to be comparable to one another.  And, I suppose, for .end to 
return a reverse style iterator even for sequences that don't support 
reverse iteration?
