The main difference: You no longer need an initial newline to enable indentation stripping, and stripping no longer removes that newline even if it is present. (Adrian Zubarev and I believe some others argued for this.) We disagreed with this at first, but it made more sense as we thought about it more. There are a few things we like about it:<br class=""><br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>1. The rules and algorithm are simpler.<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>2. It accommodates more coding styles.<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>3. Every non-escaped newline in the literal now creates a corresponding newline in the resulting string.<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>4. it's easy to get the old behavior back by backslashing the leading newline.<br class=""><br class="">Unfortunately, I think this precludes stripping the trailing newline by default, but I think this is ultimately a simpler and better approach than the previous draft.<br class=""><br class="">Other changes:<br class=""><br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* We realized we needed to make closing delimiter matching a little more complicated if we wanted to allow one or two adjacent double-quote characters that were part of the literal's contents. Oops.<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* Tabs aren't actually allowed in ordinary string literals, so we now explicitly mention that as a difference between the two types.<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* We wrote some tests for the prototype (though they haven't been updated for this new version yet). <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* There were some other wording changes, particularly in the indentation stripping rationale, but nothing that affects the actual design.<br class=""><br class="">I understand John is working on a new version of his toolchain so people can play with the prototype.
