However I still have one single concern left about the trailing whitespaces. Will the final implemented version raise a warning or produce an error when there are trailing whitespaces?</p>
<p>The whole idea of a trailing <code>\</code> was in first place to prevent new line injection but also for trailing whitespace character precision.</p>
<p>The following example could have 1000 characters, but a different developer who reads the code wouldn’t even notice.</p>
<pre><code class="swift">"""
Foo<space><space>…<space>
Bar
"""
</code></pre>
<p>That’s what the trailing backslash was meant for. To prevent unwanted whitespaces, or if you really need them, to force you to be precise about them.</p>

Foo<space><space><space>\n\

This allows a literal """ to be written \""". Discussion on the list raised the idea of allowing a line to end with \ to "escape" the newline and elide it from the value of the literal; the core team had concerns about only allowing that inside multi-line literals and felt that that could also be considered later as an additive feature.</span></div></span></blockquote></div><div class="bloop_markdown"><p></p></div></body></html>
