Jonathan Ellis commented on CASSANDRA-2355:
-------------------------------------------

Wouldn't this be more appropriate for 0.8 then?

> Being able to provide arguments to a comparator, to parametrize its behavior, can be useful.
> For example, a generic ReverseComparator is trivial to write, but without the ability to provide arguments at the comparator constriction, it cannot be used.
> CASSANDRA-2231 provides another use case for this.
> This ticket proposes to introduce a parser for comparator definition that supports optional parameters and to introduce a generic ReverseType as a simple example of this.
