yes, this is real problem, because you have to add flags and check them
every time. (Goto's really aren't that bad as I said once.)
one good solution, i think, would be this way:
while 1 do
while 1 do
exit --exit first loop
exit --exit parent loop
end while
end while
--now you have to do it this way:
while 1 do
while 1 do
doExit=true--set flag
exit
end while
--we have to check this flag *every time*, it eats up time
if doExit=true then
exit
end if
end while
Good idea, huh? 
i really like it, simple and fast.

Your idea is ok but would Euphoria not INSTANTLY break out of the nested
while loop. The second it saw a "exit" Eu would bust out of the loop and =
not
bother to look at the second one. I know its possible to change Euphoria =
so
it would read both but i dont think that EXCEPTIONS to rules in a languag=
e are
any good, one rule should apply to all, without exceptions here and there.
my 2cents

evil, corruption and bad taste

then maybe exit(2) would be better, exit(1)=exit, but i like syntax more
with prevoius, two exit statements followed.
