I am an Information Security professional with more than three decades of experience leading and supporting Information Technology. My experience includes 18 years in system administration, 22 years in Information Security and Identity Management, and 12 years in Information Technology management as an Information Security Officer.
As I recall, my goal was merely to point out that unstructured jumps are still used for error handling. I was in no way attempting to claim that the two features are the same.
One fun thing about this implementation is that labels can be passed to other functions, or returned from functions, and even used to jump back into functions that have already exited, since they are based on continuations.
Truer words were never spoken.
