Could you maybe provide some links to that effect (that this is the
convention/recommendation)? I could find nothing, (not surprising though since
the state of ANTLR's docs is, same-as-every-other-floss-project). I'm not
trying to be a pain in the ass (honest!) but this pattern is repeated
throughout the grammar and it's probably best to have this conversation once.
Also, could I get you to provide a patch against this set of patches that
implements what you are suggesting? The code above won't work for a variety of
reasons, and I wasn't immediately able to adapt it since, not to belabor the
point, but the docs weren't helpful.
Thanks Pavel!

> CQL specification and implementation for data manipulation.
> This corresponds to the following RPC methods:
> * insert()
> * batch_mutate() (writes, not deletes)
> The initial check-in to trunk/ uses a syntax that looks like:
> {code:SQL}
> UPDATE <CF> [USING CONSISTENCY.<LVL>] WITH ROW(<key>, COLUMN(<name>,
> <value>)[, COLUMN(...)])[ AND ROW(...)];
> {code}
> Where:
> * <CF> is the column family name.
> * Rows are a parenthesized expressions with comma separated arguments for a
> key and one or more columns.
> * Columns are a parenthesized expressions with comma separated arguments for
> the name and value (timestamp is inaccessible).
> What is still undone:
> * Complete test coverage
> And of course, all of this is still very much open to further discussion.
