Do not assume that these

It would be useful (and increasingly more common) to be able to match
qr|\s*(\w+)([^]*)| to qr|\s*/\1\s*|, and handle the case where those
can nest as well. Something like
listmatch this with
list
/list not this but
/list this.
I suspect this is going to need a ?[ and ?]

I am working on an RFC
to allow boolean logic ( and || and !) to apply a number of patterns to
the same substring to allow easier mining of information out of such
constructs.
What, you don't like: :-)
$pattern = $conjunction eq "AND"
? join('' = map { "(?=.*$_)" }

...My point is that I think we're approaching this
