Hello Steven,

thank you for your fast feedback and suggestions. I agreed to Matthias
to work out a more elaborated example and test suite. I'll add further
specializations as needed, if the tests expose missing once. I'll take
your hints (for units::unit) into account.

Thank you for the proposed solution for the bind problem, I'll give it a
try as soon as possible.

I'll keep you updated on the results.
