> When a function is dropped, any prepared statements which reference it need to be removed
from the prepared statement cache. 
> The default implementation of {{Term#usesFunction}} in {{Term.NonTerminal}} is not overriden
in all the places it should be. The {{DelayedValue}} classes in {{Lists}}, {{Sets}}, {{Maps}}
and {{Tuples}} may all make use of function calls.
> {code}
> CREATE KEYSPACE ks WITH replication = {'class': 'SimpleStrategy', 'replication_factor':
1};
> CREATE TABLE ks.t1 (k int PRIMARY KEY, v list<int>);
> CREATE FUNCTION ks.echo_int(input int) RETURNS int LANGUAGE javascript AS 'input';
> {code}
> a prepared statement of the form:
> {code}
> INSERT INTO ks.t1 (k, v) VALUES (?, [ks.echo_int(?)]);
> {code}
> should be dropped when {{ks.echo_int(int)}} is, but currently that isn't the case.
