Fair enough.
I would submit however that it does seem to be an ideal solution to the
challenge of command line parsing.

Much appreciated.

The docopt module converts these into strings if/when they appear in the
command line arguments.
According to the documentation these items are not quoted (which is what
I assume you are suggesting.) I did try to quote them but it made no
difference.
Thanks for taking an interest.
You are correct that only someone who has used it would likely be in a
position to offer advice.
I would never have heard about it if it wasn't for this list.
