Sorry, but I just wonder wouldn't this pointer to self structure prevent garbage collection?

  Reference cycles aren't a problem for GCs because any objects that aren't reachable from a root set of nodes are considered garbage and get collected. (I only read part of the article, but hopefully that answers your question...)

    Cool, thanks :)

    To clarify, they aren't a problem for mark/sweep GCs. Reference counting can be considered a form of GC.
