Not yet.

Sure. (And also 'foo(*a, *b, *c)'?) But have you taken a look lately at the
function definition grammar? I need some time to sort it out :)

Didn&#39;t you say it does sets too? &nbsp;Does this work?<br>
a = [1, 2, 3]<br>
{1, *a, 0, 4} &nbsp; # {0, 1, 2, 3, 
4}</blockquote><div><br>Yes.<br>&nbsp;<br></div><blockquote class="gmail_quote"

<br>
How about dicts?<br>
kwds = {&#39;z&#39;: 0, &#39;w&#39;: 12}<br>
{&#39;x&#39;: 1, &#39;y&#39;: 2, **kwds} &nbsp;# {&#39;x&#39;: 1, &#39;y&#39;: 
2, &#39;z&#39;: 0, &#39;w&#39;: 12}</blockquote><div><br>Not

<br>
Also, now that we support<br>
<br>
[*a, b, c]<br>
<br>
shouldn&#39;t we also support<br>
<br>
foo(*a, b, c)<br>
<div><div></div><div class="Wj3C7c"></div></div></blockquote><div><br>Sure. 
(And also &#39;foo(*a, *b, *c)&#39;?) But have you taken a look lately at the
