------------------------------------------------------------------
We already have pg-style strings (CASSANDRA-7769) to work around that
escape-foo. You can code any string in CQL using pg-style syntax. E.g. {code}
SELECT * FROM foo WHERE key=$$this
is
my
key$$;
{code}

> Right now the CQL grammar defines the UDF's body as a {{STRING_LITERAL}}. I
> understand that this is convenient in the grammar and avoid creating a
> special type just for these bodies. But the problem is that a quote is a
> fairly common symbol in the programming languages that will be used inside
> this body, which means that the developer will need to escape all these
> quotes in the UDF's body. That will be fairly annoying, not quite readable
> and tedious to maintain (à la backslash in Java Regexes...).
> Could we consider using curly braces or parentheses as delimiters? Though, I
> don't realize how hard it would be to use such asymmetric delimiters in the
> ANTLR grammar while still allowing them to be used within the body of the UDF.
> Another symmetric delimiter could be considered instead otherwise.
