All I can see is that it saves two characters per line—is that sufficient to warrant adding another way of doing the same thing? They're available in C/Obj-C because `+` for string literals *wasn't* available, but since Swift does support `+` for string literals, I think it's hard to rationalize adding this.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div class="m_196942562752481699bloop_original_html"><div id="m_196942562752481699bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px;color:rgba(0,0,0,1.0);margin:0px;line-height:auto"></div> <br> <div id="m_196942562752481699bloop_sign_1494941155072862208" class="m_196942562752481699bloop_sign"><div style="font-family:helvetica,arial;font-size:13px">-- <br>Adrian Zubarev<br>Sent with Airmail</div></div></div></div><div style="word-wrap:break-word"><div class="m_196942562752481699bloop_original_html"> <br><p class="m_196942562752481699airmail_on">Am 16.
