maxima woes part II:

Is the perl variable $root reserved for something special?

This problem displays (correctly)  "3" on the screen:

<problem>
<script type="loncapa/perl">
$d = &cas('maxima',"diff(3*x+1,x)");
</script>
$d <br/>
</problem>

This problem displays "$root" on the screen:

<problem>
<script type="loncapa/perl">
$root  = &cas('maxima',"diff(3*x+1,x)");
</script>
$root <br/>
</problem>

Note, that the only difference in the above is using $root rather than $d.
