[Boost-users] [boost][array] Multi-dimensional initialization

At least under MSVC 8 I can do: boost::array< boost::array<int,2>, 4 > foo = { -1,1, 0,0, 1,-1, 2,-2 }; or int foo[4][2] = { {-1,1}, {0,0}, {1,-1}, {2,-2} }; or boost::array<int,2> foo[4] = { {-1,1}, {0,0}, {1,-1}, {2,-2} }; but not boost::array< boost::array<int,2>, 4 > foo = { {-1,1}, {0,0}, {1,-1}, {2,-2} }; just wondering why this is the case.
