For this specific example, I would use:

    outer:
        loop
            execute_some_Statement_here0;
            exit when some_condition;
            execute_some_Statement_here1;
            inner:
                loop
                    execute_some_Statement_here3;
                    if some_condition_is_true then
                        execute_some_Statement_here5;
                        exit inner;
                    end if;
                    execute_some_Statement_here4;
              end loop inner;
        end loop outer;

BTW:  I also use that other language you're probably refering to, and I
almost never use continue or goto in that language either.
