<p>Piraha fails to allow things like:</p>
<div class="codehilite"><pre><span></span>$thorn = "PUGH"
ActiveThorns = "$thorn"
</pre></div>
<p>since it looks for “ActiveThorn” lines before parsing anything else of the parfile (this is in <code>src/piraha/Call.cc</code> in <code>cctk_PirahaParser</code> line 1072.</p>
<p>It should not do so since the documentation <a data-is-external-link="true" href="http://einsteintoolkit.org/usersguide/UsersGuidech7.html#x10-320023" rel="nofollow">http://einsteintoolkit.org/usersguide/UsersGuidech7.html#x10-320023</a> does not document “ActiveThorns” to be (that) special.</p>
