throw can take an argument. it can also take no arguments (its
any-type). but i thought maybe that has an error.
if it is 'catch, try 'try instead and throw an error.
if error? try[
..
if not important[throw make error! "forget it"]
..
]
'try is more often used, maybe better debugged. thats also the way
Ladislavs 'throw' works, as far as i see.
Oh, and of course there is
forever .. [
..
if not important[break]
..
]
if you are not in an inner loop.

Any problem in computer science can be solved with another layer of
indirection. But that usually will create another problem.
