Thanks Will! I tried it and it works ;) except the generic make method - i.e. can't do (make <my-struct> ...). <br><br>After looking at the defstruct code - it appears that it calls a private function called struct-type->class* and this function builds on top of struct-type->class and use it to track the slots for all the types created via defstruct and thus allow the structs to be created via made.
<br><br>I guess to fully integrate with the make method the function struct-type->class* should be exported...?<br><br>Thanks!<br>yc<br><br><div><span class="gmail_quote">On 9/6/07, <b class="gmail_sendername">Will M Farr
