> I can successfully update a List using the "literal" syntax:
> {code}
> UPDATE testcollection SET L = [98,99,100] + L WHERE k = 1;
> {code}
> And I can successfully "upsert" a List using the "Prepared" syntax:
> {code}
> UPDATE testcollection SET L = ? WHERE k = 1
> {code}
> by providing a decoded List<Integer> in the bind values.
> But using the "prepared" syntax for an prepend like:
> {code}
> UPDATE testcollection SET L = ? + L WHERE k = 1
> {code}
> fails with the following message:
> {code}
> java.sql.SQLSyntaxErrorException: InvalidRequestException(why:line 1:33 mismatched input
'+' expecting K_WHERE)
> 	at org.apache.cassandra.cql.jdbc.CassandraPreparedStatement.<init>(CassandraPreparedStatement.java:92)

> {code}
> and an append of a "prepared" syntax like:
> {code}
> UPDATE testcollection SET L = L + ? WHERE k = 1
> {code}
> fails as follows:
