 ### Break/Continue Semantics
 - BREAK unwinds to frame that called the iterator function
 - Multiple nested function calls: break exits all of them until reaching marked frame
-- CONTINUE requires explicit continueAddress in frame (set by compiler for loops)
+- CONTINUE is implemented by the compiler using JUMPs
 
 ### Exception Unwinding
 - THROW unwinds call stack to handler's depth, not just to handler
