Dear John B.,

  Thank you, that was very helpful.  To summarize those messages,
a majority on COMCIFS made a proposal to make the treble-quoted
strings agree with those of Python.  The reasons given were:

"such informal
descriptions are never as reliable as an actual implementation,
in particular one that's been around for many years and is used
by millions of people."  (Ralf)

  "meaningful adoption of DDLm/CIF2 will require embracing
and leveraging existing technologies as much as possible." (John W.)

"I find it [counter-intuitive] and unproductive to adopt something
that looks very much like the python treble quoted
string but which follows confusingly different rules." (HJB)

The responses you cite did not seem to address those issues.  Was
there a discussion on those issues that I missed?

Regards,
    Herbert
