Reference

A simple wrapper class which contains a reference to a value of the given type. The main usage is to wrap primitives to modify them inside closures.

function limited_sum(LinkedList someList) returns real
	let dist_ref = reference(0.)
	someList.for_each() (real elem) ->
		if dist_ref.val < 500
			dist_ref.val += elem
	// Destroy the reference and use the contained value.
	return dist_ref.into()

Make sure to destroy references if you don’t need them anymore.
