> 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.
