In working on adding bitwise &/| operators for counts, I've come across apparently undocumented && and || operators for patterns:
p1 && p2 yields a pattern that matches a p1 followed by a p2 p1 || p2 yields a pattern that matches either p1 or p2 Confusingly, Bro also supports "p1 | p2", which means the same as "p1 || p2" above, but *only* if p1 and p2 are literal patterns, not if they are variables of type "pattern". (This functionality is in common use.) It doesn't support "p1 & p2" in any form. I searched a large corpus of scripts and didn't find any instances of "p1 && p2" or "p1 || p2" for literal patterns, so I suspect the current feature is basically unused. Proposal: as part of adding bitwise &/| operators for counts, I'll also implement &/| operators for patterns, and remove the current &&/|| functionality. This seems pretty straightforward to me - but I've mistakenly thought that about other things before! :-P So if anyone has comments, plz speak up ...
