[Boost-users] [mpl] resulting sequence limits

Hello, I've got 2 mpl::map's, both have less than 20 elements. I copy one to another, and the result has more than 20 elements. I thought that BOOST_MPL_LIMIT_MAP_SIZE macro affects only explicit definitions of maps, not result values of metafunctions, but it turns out that the above case doesn't compile -- until I #include <boost/mpl/map/map30.hpp> Is it behavior "by design", or is it a bug? Thanks.
