I don't know, but my guess is that perl simply keeps a pointer to the array-element it is at in the loop. I did a few tests with splice and perl did exactly what I expected from it. It looped over the array positions (!! not the array values) until it was outside the array length (because of looping or a shrinking of the array).

Would be nice if someone could show me a case where perl gets confused. I could not create one
