contrib/cube has an arbitrary limit of 100 on the number of dimensions in a cube, but it actually enforces that only in cube_in and cube_enlarge, with the other cube creation functions happy to create cubes of more dimensions.
I haven't actually tested, but this implies that one can create cubes that will break dump/restore. Should this limit be kept, and if so what should it be? (There's obviously a limit on the size of indexable cubes) (Noticed because an irc user was trying to use cubes with 512 dimensions with partial success) -- Andrew (irc:RhodiumToad)
