(Childish flame alert?)  You want to see contorted code?  Look at someone
trying to wrestle out of Pascal's loop constructs with boolean flags.  At least
with lots of goto's you've only to worry about one state: where you are in the
program.  With this code, you have to cross this with the possible combinations
of flags.  I want to call the style police when i see this (and don't even
think about nested loops):

done := false;
while not done do begin
        do_some;
        if done_now then
                done := true
        else
                do_some_more;
                if done_already then
                        done := true;
                { leaving out the else causes a mess }
                do_even_more
end
