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 = new 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.
Consumes the reference, destroying it and returning the contained value.
