> The CQL grammar ({{Cql.g}}) is currently a composite grammar and, as such, is not easy to extend.
> We now have a number of 3rd parties who are extending the grammar (custom index grammars, for example) and it would be helpful if the grammar could be split in a parser and lexer in order to make extension easier.
