> When a SyntaxError is returned, including a snippet of the query close to the
> error would make a lot of error messages easier to understand. For example,
> if you did this with the python driver:
> {code}
> session.execute(SELECT * FROM users WHERE username='%s', ['Joe Smith'])
> {code}
> you would wind up with an extra set of single quotes (the driver
> automatically escapes and quotes input). If a snippet like {{...WHERE
> username=''Joe Smith''}} were included in the error message, this would be
> pretty easy to spot.
