If you're going to do it then do it that way that you can create as many
objects as you want in a loop, I don't know how exactly should it work,
something like this:

include circle.e as CIRCLE

sequence one_object

CIRCLE one_object
for i = 1 to 100 do
    one_object = new (CIRCLE)
    objects = append (objects, one_object)
end for
