I'm outputting a comma separated list within a
forEach iterator and want to append a comma
after all elements, except the last. I thought
that a simple conditional statement might do this: i.e.:

self.elements->forEach(element) {
if (position() + 1 < self.elements.size()) {

However, the use of arithmetic expressions in
sub parts of logical expressions seems not to
be allowed and the above gives me a syntax error.

As an alternative I factored out the arithmetic; i.e.:

var lastPosition = self.elements.size() - 1
self.elements->forEach(element) {
if (position() < lastPosition) {

Although this works for this example, I now need to
filter the collection and the last element output may
not be at the end of the collection. So, I need a
something like a MOFScript function that indicates
when the last element in the collection is being

Does anyone know a better approach for the
simple case or how to do the more complicated one.
