> During the development of CASSANDRA-11053 we have added changes to the cqlsh formatting code so that we can format {{blob}} types correctly even if they are represented as {{str}} rather than {{bytearray}}.
> At the moment we ensure {{blob}} are of type {{bytearray}} via the following shortcut:
> {code}
> cassandra.cqltypes.BytesType.deserialize = staticmethod(lambda byts, protocol_version: bytearray(byts))
> {code}
> After CASSANDRA-11053 is committed there will be a similar shortcut to override the fast serializers implemented in cython. 
> Decoding the CQL type is safer in that it decouples cqlsh formatting from the types returned by the driver deserializers but it is also unnecessary for CASSANDRA-11053 performance goals and risky for older releases. 
> Therefore this ticket delivers this functionality but only on trunk.
