</div></div>Good work! It&#39;s nice to see introductory documentation for abcl.<br>
<br>
Now the (constructive) criticism part :) I found an inaccuracy on<br>
Slide 10, regarding boxing/unboxing of values. Indeed boxing and<br>
unboxing is done automatically by ABCL. In your case, had you wrapped<br>
your ints in Fixnums instead of JavaObjects, you could have used them<br>
directly in Lisp. In general, since the user can&#39;t be expected to know<br>
how to map every Java type to Lisp and vice-versa, there are a couple<br>
of nice methods you can use in all cases:<br>
<br>
public static LispObject JavaObject.getInstance(Object, boolean)<br>
converts (or wraps) a Java object to a Lisp object, if the boolean is<br>
true (else it just wraps it in a JavaObject).<br>
<br>
public Object LispObject.javaInstance()<br>
converts (or unwraps) a Lisp object to Java. You can invoke this on<br>
any Lisp object, if it can&#39;t be converted, it will be returned as-is.<br><br></blockquote></div></div>
