    Me too.  Thanks.

    The counted string vs. null terminated string issue
turns out to be complicated.  If you use only
null terminated strings, appending a char to a
string becomes very expensive, and "end()" is
expensive to evaluate.  If you use only counted
strings, the interaction with subscripting is
non-obvious.  If you store a null, what happens?
Are you allowed to store beyond the current length
in use?  Mixing C string and <string> semantics
is messy.  I ended up with a lazy evaluation scheme.
