No. I was not aware that it is possible to do this. I have now adopted
   struct char_string
   {
      ...
      virtual iterator iter_offset(different_type) = 0;
      virtual const_iterator iter_offset(different_type) const = 0;
   };
into my implementation.

Q: Since the above is valid C++, is the following?:
   virtual void myfn( char ) = 0;
   virtual void myfn( int, bool ) = 0;

Because I had assumed that you could not do this, since (1) I haven't read 
the standard that properly, I have mainly focused on learning from other 
books (like Stroustrup, 3ed) and (2) I haven't seen any code that uses 
virtual functions like char_string above or my question.

Reece
