Collections are more or less implemented the exact same way. I'm pretty much tired of writing them, so I am putting them all into a Standard Collections thread. This will not have more complicated collections like Splay Trees, AVL Trees, B-Trees, B+Trees, Red-Black Trees, and so forth because they are more complicated than the basic standard collections and they should go into their own threads.

JASS:
module Stack
    readonly thistype next

How many times have I mentioned that readonly doesn't protect module elements from being set by the implementing struct? Well it is pretty useless to add readonly since you are not protecting the user in any way. The only way to do this is to make "next" private and make a "get" operator for it.
