No, it is not clear to me how to use your library.

Try putting yourself outside of your actual knowledge of what you are
doing and try to think in practical terms of what the end-user would
need to understand and know to use what you have created.

Of course if you are just writing a library mainly for yourself with
just some incidental documentation on what that functionality is all
about then you are not that interested in having others consider your
software for themselves unless they are willing to do a great deal of
digging into the actual code to understand it. I am not willing to do
that sort of digging. Maybe many others are, I really don't know.

You are correct about CXXD. My ambitions are for it to be used with any
level of C++ and with any dual libraries where a great deal of the
syntax and functionality are the same, without having to be a perfect
match in all respects; and for it to be easy to use. if it is misused I
don't think it will be because the documentation is lacking. At the same
time I am very open to any improvements that can be made in CXXD within
its scope of macro programming.
