Hi,<br>I have a need to represent a directed graph in XoTcl.<br><br>&#39;-childof&#39; functionality seems to work well to represent trees.<br>Unless I misunderstand,&nbsp; it seems this will force an class-object to belong to a single parent  (1-to-many relationship).
<br>Is there a way to represent multiple parents (many-to-many relationship) without making multiple copies of nodes along the way?<br><br>Any help is appreciated. <br><br>thanks,<br>-shishir<br>
