Aleksey Yeschenko commented on CASSANDRA-8879: ---------------------------------------------- Given that we can only do it for three types at best (blob to ascii, blob to utf8, blob to inet), I don't think making any exceptions, even if you pinky-promise that the types truly match, and introducing special syntax, is the right way to go.
