"do...over" works by requesting an array causing the method "makearray" to be invoked which is
available for all collections due to being defined in the .collection class.
ooRexx 5.0 introduces the ability with "do with ... over" to iterate a supplier object. If the
object to iterate is not a supplier it gets requested from the collection. However it seems that it
does not follow the ooRexx request protocol (method request in the root class .object) which would
need a method "makesupplier" to be defined in the .collection class as well. This would also allow
for implementing one owns classes that supply the method "makesupplier" to become usable for "do
with ... over".
