+
+ \brief Determines if a sequence is a Boost pplib list.
+
+ The macro checks that the sequence is a pplib list.
+ It returns 1 if it is a list, else if returns 0.
+
+ sequence = input as a possible Boost PP list.
+
+ returns = 1 if it a list, else returns 0.
+
+ The macro will generate a preprocessing error if the input
+ is in the form of a list but its end-of-list marker, instead
+ of being an identifier, is a preprocessor token which VMD cannot parse,
+ as in the example '(anything,&BOOST_PP_NIL)' which is a valid tuple but
+ an invalid list.
