Okay I'll take it out.
The performance hit for a list of ints is 2.7% (i.e. it takes 2.7%
longer without memoing). With a list of values of mytype (see below)
it takes 27.2% longer.
:- type mytype
---> mytype_functor(another_type2, another_type3).
:- type another_type2
---> another_type2_functor(int).
:- type another_type3
---> another_type3_functor(int).
Ian.
