Description

I sometimes find myself wanting to abuse Cassandra datatypes when I want to interleave two different types in the same column.

An example is in CASSANDRA-6167 where an approach is to tag what would normally be a numeric field with text indicating that it is special in some ways.

A more elegant approach would be to be able to explicitly define disjoint unions in the style of Haskell's and Scala's Either types.
