Hi there,

 I am looking at:

http://www.boost.org/doc/libs/1_39_0/libs/preprocessor/doc/ref/tuple_to_list.html

 Just ouf of curiosity why is size required ? Can't the number of
argument be deduced using the preprocessor ? Eg.:

http://groups.google.com/group/comp.std.c/browse_thread/thread/77ee8c8f92e4a3fb/346fc464319b1ee5

Boost PP uses C++ preprocessor. Variadic macros are not part of it, but they are part of C99 and many C++ compilers support it. AFAIK there is no way to get size of a tuple without variadic macros.
