kwaping,
I suggest we start exploring that path.

That is the whole point of the question. I am using the special form of goto for an optimization. I am wondering why it breaks. I am even more interesting in why changing it from one sort prototype to a different sort prototype, it starts working. In case you were wondering, the prototypes I am referring to are for sort and not the user-defined comparator sub you referred to elsewhere in this thread.

With regards to your update. I think that is referring to goto label where you are actually trying to exit the routine. Using the special goto &sub you are immediately resuming execution after replacing the current call stack. At least that's my understanding of it. If that wasn't the case then neither example should work. At this point, I throw my hands up.

Cheers - L~R
