If the \ operator is not defined in swift, does it treat it as something that can be operator overloaded?<br><br><br><div class="gmail_quote"><div dir="ltr">On Sun, Feb 5, 2017 at 10:29 AM Nicolas Fezans via swift-evolution <<a href="mailto:swift-evolution@swift.org">swift-evolution@swift.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class="gmail_msg">Dear all,<div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">This is a rather simple proposal to add '\' (backslash character) as a valid operator-head in the swift grammar.</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">One argument for it, is that there exist a backslash operator in the MATLAB/Scilab/Octave languages.

If that is the case, both uses should never generate a conflict or be ambiguous, isn't it? (String literals keep their interpretation of \ and \ used otherwise within the swift code will be interpreted as an operator or as the beginning of an operator)</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">I am curious to see what will be the feedback on this.</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">Nicolas</div></div>
