Tried to address these comments by Dave:
The section on "special" keywords links to a part of the parameter lib
tutorial that no longer exists. It also says "Therefore we need to tag the
color keyword as a special keyword" but it never shows how to do such tagging!
The whole thing about the forwarding function objects is unclear. You show
one example, but you don't explain why it's needed and you don't explain the
rules by which it was constructed, so it's not obvious how I would define my
own.
Work in progress.
