----------------------------------------------------------------------------
I experimented a bit and the behavior Is quite inconsistent. According to
CASSANDRA-16240, in Ubuntu the newly created table should appear in "" when we
run _describe tables;_ This is not the case on my Mac. Not sure whether
something somewhere has been also changed since that ticket.
Below is some output to show the current behavior. Seems like all operations
would work but we should put _reserved_keywords in ""_ when we do _DESCRIBE_ or
_USE_.
I think that the best would be really this to be fixed on the driver side.
[~aholmber], do you know by chance if
[PYTHON-1270|https://datastax-oss.atlassian.net/browse/PYTHON-1270] is planned
for work soon?

>
> Based on the information
> [here|https://github.com/apache/cassandra/blob/cassandra-4.0-rc1/doc/source/cql/appendices.rst]
> from the Cassandra 4.0 RC1, "config" is not a keyword, and certainly is not

> I believe this is a bug in cqlsh 6.0.0, because it behaves the same way when
