Would it not be easier to simply prevent mixing of the two concepts 
(continue, and leaked local), afterall the compiler should be able to 
determine if there's a reference to a block local in the termination 
condition, and also whether there was a continue to restart the loop? As 
a language user I'd find the ability to use continue in two out of three 
types of loops bothersome (especially because I dislike the scope change 
from 5.1 and would use the 5.0 style external local).
