No, just that I didn't have the other syntax on my radar.  I was looking
at Snort & Suricata and didn't find this; I'm not a PCRE user myself.
It's simple to change, will do so now (though I think mine is slightly
more cool ;-).

Just so I have this right: it looks like the preferred would not be
/(?i foo)/ but rather /(?i)foo/, yes?
