My confusion comes from the fact that I did not realize that Fit was
actually defining a function. I thought instead that Fit was taking a
Callable and ghenerating another Callable when using Fit's
functionality, in much the same way that boost::bind does. I know that
the macro in Fit is called BOOST_FIT_STATIC_FUNCTION ( or
BOOST_FIT_STATIC_LAMBDA ) but the term 'function' in the Fit
documentation is so often used when Callable is the actual correction
designation that I thought that this was one more instance of this
usage. Thanks for straightening me out with your explanation.
