| Description |
| ----------- |
| |
| ``BOOST_MPL_LIMIT_MAP_SIZE`` is an overridable configuration macro regulating |
| the maximum arity of the ``map``\ 's `variadic form`__. In this |
| implementation of the library, ``BOOST_MPL_LIMIT_MAP_SIZE`` has a default value |
| of 20. To override the default limit, define ``BOOST_MPL_LIMIT_MAP_SIZE`` to |
| the desired maximum arity rounded up to the nearest multiple of ten before |
| including any library header. |preprocessed headers disclaimer| |
| |
| __ `Variadic Sequence`_ |

| Example |
| ------- |
| |
| .. parsed-literal:: |

| #define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS |
| #define BOOST_MPL_LIMIT_MAP_SIZE 10 |
| ``#``\ include <boost/mpl/map.hpp> |
| ``#``\ include <boost/mpl/pair.hpp> |
| ``#``\ include <boost/mpl/int.hpp> |
| |
| using namespace boost::mpl; |
| |
| template< int i > struct ints : pair< int_<i>,int_<i> > {}; |
| |
| typedef map< ints<1> > m_1; |
| typedef map< ints<1>, ints<2>, ints<3>, ints<4>, ints<5> |
| ints<6>, ints<7>, ints<8>, ints<9>, ints<10> > m_10; |
| |
| // typedef map< ints<1>, ints<2>, ints<3>, ints<4>, ints<5> |
| // ints<6>, ints<7>, ints<8>, ints<9>, ints<10>, ints<11> > m_11; // error! |
