OK, you are, of course, right. The output of the query in QuiP is as follows:
<out>
<one>True</one>
<two>False</two>
</out>
If I remove the curly braces, I get:
<out>
<one>$a == $a</one>
<two>$a == $b</two>
</out>
So the output I posted did not match the query I posted. I'm not sure what
I did while writing that email, but the query works properly in QuiP.
