Yes. I din't use goto 5 years :-). Continue stmt is more cleaner and 
readable.

now:   FOR i IN 1 .. 100 LOOP    continue := true    WHILE continue LOOP      ...      EXIT; -- contine      continue
:=false; -- really exit    END LOOP;  END LOOP;       
 
with continue
 FOR i IN 1 .. 100 LOOP   ...   EXIT WHEN ..   CONTINUE WHEN .. END LOOP;

One argument for continue inside begin block - for discussion only.
on loop exit means break iteration, continue new iteration. Continue and 
Exit are symmetric.

I didn't know ADA haven't continue. In PL/pgSQL there isn't any problem 
implement continue stmt (wit any face), but goto stmt means relative big 
changes in source code.
