> In the current master, sometimes it's too confusable to represent JSON and regex in a string literal if they contain backslash.
> For example, in JSON, \ needs to be escaped like as follows.
> {code}
> {"a": "\\"}
> {code}
> But, if the JSON above is represented in a string literal, further two \ are needed because string literal also requires \ to be escaped.
> {code}
> SELECT from_json('{"a": "\\\\"}', 'a string')
> {"a":"\"}
> {code}
> To make such case simpler, it's great if Spark supports raw string literal.
