As a result of pre-review comments, the Filesystem Library just reviewed 
had const stuck on a bunch of member functions which return by value but 
take no arguments.  For example:

       const iterator begin() const;

What is your take on that? Any different from the case where the returned 
value is a modified pass through of an argument?
