      OK, this works. I shudder to think of the reasons why...

      Sigh... I started the first thread while trying to use a templated 
function object...

      I guess it would help if the syntax for all four possibilities 
(normal function, templated function, normal function object templated 
function object) made it into the Boost.Test documentation.

   At any rate thank you very much!
