</span>+1. It seems weird to add a whole new precedence level when an<br>
existing one works fine. Accidentally negating a future/deferred is<br>
not a significant source of errors, so I don't get why that would be a<br>
justifying example.<span class=""></span><br></blockquote></div><br></div><div class="gmail_extra">You can call me weird, but I *like* fine-tuning operator binding rules to suit my intuition for an operator. 'await' is not arithmetic, so I don't see why it should be lumped in with '-'. It's not like the proposed grammar change introducing 'await' is earth-shattering in complexity.<br clear="all"></div><div class="gmail_extra"><br>-- <br><div class="gmail_signature">--Guido van Rossum (<a href="http://python.org/~guido" target="_blank">python.org/~guido</a>)</div>
