--------------------------------------------------------------------
I have introduced the *IGenericFunction* to support hard-coded generic
functions without adding more special cases to *Selectable* as you suggested.
Then, the jar loading mechanism allows to add some generic functions not
provided in the Cassandra project (like my wierd toString() function, or any
other...). I agree, it's more like an extension point rather than an UDF. Such
extension could also be loaded from the configuration file or the CQL schema,
or other things....
Regarding the security, anyone accessing the lib directory of C* can introduce
a backdoor in any jar files, so, loading functions from a jar in this lib
directory does not change the game, it's up to the C* admin to properly
restrict access to the lib directory.
