I don't get what you mean here. qw/ac qw/ and qw/ca qw/ are treated identically by the flip-flop operator:

Yes, I know that. Also the description on perldoc seems clear if you already know what to expect. My whole point is that the result of perl -we'my @l = qw/ca qw/; for (@l) { print if /a/../c/ }' is not logical.

Suppose that I want to process html file where I have tags like this:

<tag> a </tag><tag> b </tag><tag> c
If my flip-flop condition is /<tag>/../<\/tag>/ it would print
<tag> a </tag><tag> </tag><tag>
which is not what you want. With three dots you get
<tag> a </tag><tag> </tag><tag> c </tag>
still not good :(

Basically, what I originally (and incorrectly as I see now) expected from this operator was that it processes each element char by char (as a real flip-flop) and not as a whole. Of course, in my html example I can first format the file but that is another story.

BTW: I am new here and have a question about writeup formatting. How do you cite someone's text if it contains a code? Copy-pasting and than manually putting those code tags back (which I did) seems pretty tedious.

    If you have the latest firefox,
    select the text, right context menu, View selection source
    then paste into your textbox where you have a convenient template of

    <blockquote><i> quoted </i></blockquote> <p> response </p>

    or
    <p><i> quoted </i></p> <p> response </p>

    or
    <dl> <dt><p> quoted </p></dt> <dd> response </dd> </dl>

    Sure, it will no longer be download-able code but no matter

    The alternative is to use the xml link ( ?displaytype=xml;node_id=980252 ) and copy/paste from the original
