If you're really desperate, put a <<LABEL>> and a NULL; before your END LOOP statement, then GOTO

  1 begin

  2     for counter in 1..10 loop
  3             dbms_output.put_line(counter);
  4             goto brk1;
  5             dbms_output.put_line('didnt branch');
  6     <<brk1>>
  7     null;
  8     end loop;

  9* end;
