There are many practical and pragmatic reasons to want to embed multi-line string literals in code, and most of these use-cases are hampered or made more significantly more fiddly with continuation characters or concatenation, for all the reasons already discussed.<br class=""><br class=""><blockquote type="cite" class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>• Does this proposal fit well with the feel and direction of Swift?<br class=""></blockquote><br class="">This is where things break down. This proposal feels like we took Python’s approach and slapped it on Swift. There are more ways to do this than identical open-close delimiters with magic whitespace stripping. </div><div class=""><br class=""></div><div class="">Non-exhasutive ideas for other options we should weigh (all spellings are straw-men):</div><div class=""><br class=""></div><div class="">1.
