I think I read recently that using the Oracle (+) operator can give you the error "cannot outer join to more than one table" if you try to outer join to two or more, but the ANSI syntax will allow you to do that - I really should test this out ...
edit - I tried this out and right now cannot get that error, so not sure where I got that idea from.
