Under some circumstances, users will be expected to include only a few of the
function[0-9].hpp functions but not function.hpp.

Binary compatibility is the most often-cited reason for having the
function[0-9] classes... If the "function" class is expanded from 9 to 12
arguments, everything that uses "function" directly will need to be
recompiled. However, if functionN classes are used, no recompilation is

Perhaps a more thorough treatment of the numbered classes should be added to
the documentation with the binary compatibility argument.
