F(R,X) usually expands to a tuple of the same number of elements.
- <B>I</B> is the state instantiation macro.
- <B>R</B> is the recursion depth and should only be used as a parameter to
other macros implemented using BOOST_PP_FOR() or for invoking
BOOST_PP_FOR##R() directly. For each macro implemented using BOOST_PP_FOR(),
there is a version of the macro, distinguished by the R suffix, that accepts
an additional recursion depth as the first parameter. This technique is
necessary to avoid recursively expanding the same macro again, which is not
permitted by the C++ preprocessor.
