Hallo,<br>

<div><div class="h5">&gt; Hi,<br>
&gt;<br>
&gt; I can see sometimes these kind of procedures ##car, ##cdr, ##null? etc... in<br>
&gt; code that has been optimized for Gambit. What is exactly the difference<br>
&gt; between those and the standard ones? And if these ones are faster, why are<br>
&gt; they defined as separate functions instead of just substituting the standard<br>
&gt; ones when in (unsafe) compilation? Then, how are they really used?<br>
<br>

Segmentation fault<br>
