Oh and to follow up on this, so in PCRE does /x((?i)bar)foo/ make the "foo"
part case-insensitive too, or not? It's not obvious to me from the page
you pointed me at, and I don't have an environment set up to definitively
It does not. So:
/x((?i)bar)foo/ is (kind-of ) equivalent to /x(?i:bar)foo/ and only makes the bar
part case insensitive.
/x(?i)barfoo/ would make barfoo case insensitive.
I am fine with implementing either (?[flags]) or (?[flags]:[pattern) or
I hope this makes sense.
: Kind-of, because (?i:bar) is non-capturing, whereas ((?i)bar)
captures "bar" in the first capture-variable. Since we don't support
capturing at the moment that does not really matter for us - it might be
of importance in the future though.
