While I suggested something like those, I would also suggest that the
existing operators for inet/cidr be taken into consideration:
 x >>= y  "x contains y" x >> y   "x strictly contains y" x <<= y  "x is contained in y" x << y   "x is strictly
containedin y"
 

(obviously these don't all necessarily make sense for all types)

These have the advantage of resembling set notation more closely and being
in use in one existing core type.
