David, thanks for your comments, they are very good.  I'll look them
over and respond tonight when I have more time to formulate meaningful
answers.

I don't feel the effort was wasted.  Two of my personal goals for
doing it was to spur getting NTPs into Boost but also to have a
vehicle for me to learn about mpl.  The former seems to have been
accomplished and the latter most definitely was.  :)

I didn't actually write 400 tests, the computer did.  :)  I have a Perl
script that walks through all possible combinations of specifying (or
not) parameter values for a three-argument template.  I could probably
adapt the script for named_parameters fairly easily once I understand
the interfaces.  Given my brief scan of your comments it probably won't
generate 400 tests because my understanding is that there are some
restrictions in your implementation about how unnamed/positional
parameters are bound.  That's not a criticism, just something to keep
in mind when counting tests.
