I don't think it's important that it be at the top of the file, but it does
need to be a keyword.

I think it&#39;s impossible to have per-file without making &quot;use&quot;=
 a special keyword, ideally at the top of the file. The block syntax made m=
ore sense to me because I knew exactly when it started and ended, and a &#3=
9;use&#39; later in the file did not affect code that came before it. Also,=
 the example where I have both a namespace and a &#39;use&#39; in the same =
file would be impossible if the use applied to the whole file.<br>

<br>
I&#39;m willing to mock up anything else we want to try, including a whole-=
file version.<br>
