<p class="MsoNormal"><span style="mso-fareast-language:EN-US">My only question is: do we really need a flag. Suppose we simply accepted the postfix “qualified” with no flag support. Then a program will be accepted that earlier compilers would have rejected
– and, absent a flag, we normally try to continue to reject programs that weren’t legal before. But in this case no one is going to fall into this by mistake. I suggest we consider simply allowing it as an exception to our general rule, and move on.<o:p></o:p></span></p>

<p class="MsoNormal">I think it's widely accepted that the original syntax was a mistake. I don't need to rehash the rationale for the change here, iit's described pretty well in the proposal and elaborated in the discussion.<o:p></o:p></p>

<p class="MsoNormal">The question for us is really: is it worth changing? There are costs:<o:p></o:p></p>

<p class="MsoNormal">- A new extension flag, which itself has costs (extra documentation, a new thing that people need to understand)<o:p></o:p></p>

<p class="MsoNormal">- new code using the extension doesn't compile with older compilers<o:p></o:p></p>

<p class="MsoNormal">Personally, the current syntax annoys me almost every day. It's already a small cost on everyone, and I think we need to move forwards even if there are costs in migrating. So, I'm going to recommend that we accept this proposal.<o:p></o:p></p>

I suggest you make a recommendation, in a new e-mail thread with the<br>
proposal number in the subject, about the decision, maybe point out<br>
debatable points, and assume that anyone who stays quiet agrees with<br>
you.<br>
<br>
Thanks,<br>
