I guess it'd be 20 copies of the object. Thus, the macro-parsing is
saved. But CSG-Objects aren't saved like meshes, where the mesh
is loaded into the memory once, and then simply referenced. You
will have 20*CSG objects loaded into memory, no matter how you
do it (via macro or just copying), but macros create overhead.
