Sylvain Lebresne commented on CASSANDRA-7396:
---------------------------------------------
Not really a fan of the {{?}} variants: you can just query and see if it
returns null and it's not standard enough that it's worth cluttering the syntax
with (we can always provide a {{isNull}} method if we really want to).
Regarding the slicing syntax, I guess it's not crazy for maps and sets but I'd
much rather not adding anything for lists because 1) I don't think there is any
easy way to optimize this under the hood and 2) I'm not all that convinced that
it's that useful in practice.
