I don't like something that is a standard operator becoming
special syntax. While it's true that string & string is not
valid, it's not the case that string & ... is not valid. I
dislike dot for the same reason. It's confusing that these would
do different things:
<div>
<br>
</div>
<div><font face="courier new, monospace"> 'abc' & 'def'</font></div>
<div><font face="courier new, monospace"> ('abc') & 'def'</font></div>
<div><br>
</div>
<div>
<div>I like the \ idea because it's clearly syntax and not an
operator, but the fact that it doesn't work with comments is
annoying since one reason to break a string is to insert
comments. I don't like that spaces after the \ are not allowed
because trailing spaces are invisible to me but not to the
parser. So what if the rule for trailing \ was changed to:<br>
<div><br>
</div>
</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div>
<div>The \ continuation character may be followed by white
space and a comment. If a comment is present, there must
be at least one whitespace character between the \ and the
comment.</div>
</div>

<div>That is:</div>

<div><font face="courier new, monospace">x = [ # THIS WOULD
BE ALLOWED</font></div>
<div><font face="courier new, monospace"> 'abc' \</font></div>
<div><font face="courier new, monospace"> 'def' \ #
not the python keyword</font></div>
<div><font face="courier new, monospace"> 'ghi'</font></div>
<div><font face="courier new, monospace">]</font></div>
<div>
<div><br>
</div>
<div>
<div><font face="courier new, monospace">x = [ # THIS
WOULD BE AN ERROR</font></div>
<div><font face="courier new, monospace"> 'abc' \</font></div>
<div><font face="courier new, monospace"> 'def' </font><font
face="courier new, monospace"># a comment but no </font><span
style="font-family:'courier new',monospace">continuation </span><span
style="font-family:'courier new',monospace">\</span></div>
<div><font face="courier new, monospace"> 'ghi'</font></div>
<div><font face="courier new, monospace">]</font></div>
<div><br>
</div>
<div>One thing I like about using \ is that it already
works (aside from my proposed comment change). So
anyone wanting to write forward/backward-compatible
code can just add the \s now. If you want to start
enforcing the restriction, just use from __future__
import explicit_string_continuation.</div>

<font face="arial, helvetica, sans-serif">Right, that's a good one!<br>
Although I hate the backslash from bad experience with windows.<br>
But actually the most reason that I always hated to use "\" for
continuation<br>
lines is its strict behavior that does not allow any white space
after it.<br>
<br>
Hey, it would be great if that proposal makes it !<br>
