Actually, no.  You must have been looking at the
example programs.  (I should have made that clear in
the synopsis of each class/function that had an
example.)  The Core Library itself never defines
BOOST_PARAMETER_MAX_ARITY; instead, each header file
defines an internal macro that requirest
BOOST_PARAMETER_MAX_ARITY to be at least a certain
value; this macro is #undef'd at the end of the header
file.
