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 
necessary. 

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