[Boost-users] What help can Boost offer?

I often want to express intent of this sort... struct X {...}; void f( X & ); X my_array[3][6][11]; for (unsigned i=0;i!=3;++i) for(unsigned j=0;j!=6;++j) for(unsigned k=0;k!=11;++k) f( my_array[i][j][k] ); Apart from all the grottiness on hardcoded sizes and loop indices, which is just for exposition, is there a nice idiom in boost to do traversals over multiple indices in this way, or perhaps multiple ranges? Thanks, Rob.
