What we have seen with tolog is that it would be great if the  
association predicates could put the matching association into a  
variable. With something like, say,

   $a = member-of(member: $p, group: $g)

it would be easy to use the path language for working with reification  
and scope on the association. It would also be easy to get hold of the  
association for editing/deletion etc.
