Hello Swift community,
The review of SE-0200: “Raw” mode string literals ran from March 16...26, 2018. The proposed is returned for revision, and should be further discussed as a pitch to coalesce further before coming up for review again.
During the review discussion, a few issues surfaced with the proposal, including:
- 
The proposed r"..."syntax didn't fit well with the rest of the language. The most-often-discussed replacement was#raw("..."), but the Core Team felt more discussion (as a pitch) is necessary.
- 
The proposal itself leans heavily on regular expressions as a use case for raw string literals. Several reviewers remarked that the motivation wasn't strong enough to justify the introduction of new syntax in the language, so a revised proposal will need additional motivating examples in other domains. Thank you, 
 Doug
