>About the allocator template parameter, that is my original design.

I like the design you proposed below. How can I help you with this?
Please let me know what I can do to help you. For instance, I could try
to do the test infrastructure, but perhaps you have plans for that as
well.

this, plus

>  };

plus the __cxa_demangle bits as posted/sketched look swell. I think this
looks good.
