Re^3: Need explanation: what \$_ and ${} do

[chester]

    s   Treat string as single line. That is, change "." to match any
        character whatsoever, even a newline, which normally it would not
        match.

There are no .'s in the regex.

... which makes me learn that [^>] does match a newline :)

Thanks for bothering, chester!
