 James Davenport suggested that we introduce new lifting operators that
 lift associative operators to their -coll and -expr forms.

 For instance we have the

 DefMP: union-coll := lift-collection(union)

 FMP: lift-collection(O,O(A,B)) = O(lift-collection(O,A),lift-
 collection(O,B))

 for the only assiciative operators we will need a lift-list operator and
 for the ACI operators a lift-collection

 Furthermore, we will need a pair of lifting operator for making -exp
 operators.
