Dear Masklinn,<br>
<br>
thanks for your suggested solution.<br>
<br>
I know all of these, but<br>
1) it is not as elegant or short<br>
2) why does unpacking not work syntactically the same as for the function<br>
parameters?<br>
It seems a natural extension that appears not to have a syntactic<br>
conflict. If it is not even a necessity for consistency.<br>
<br>
So, the point is not that something like<br>
[0,*x,0,*y,0]<br>
can't be done in other ways, but that it can't be done in a neat way.<br>

I quite like that (suggested) syntax.<br>

So do I. But I question the need for it.<br>
