I don't at first see how to do this in the BCs, where the
Container_Type and Iterator (BTW, if you are going to say
Container_Type, eew, why not Iterator_Type?) are abstract ..

but there would be no point anyway unless I make the major change of
supporting the STL/Charles view of iteration, and the likelihood of
that is minimal.
