We recommend applying all changes to filters and goals to a sandbox profile before applying them to your main profile. We are not responsible for data that gets irretrievably lost or reformatted because of regular expressions you tested here. If Google Analytics ever changes their regex engine, they wouldn't necessarily tell us about it.
