Wait, something is coming through. I am getting an idea; nay, a premonition. I see...a future where Perl exists entirely between a / and a /, a world held between two edges of a crevice. A world where we lose our conscious knowledge of when the regular expression begins and ends, of where it should and should not, as choice becomes too intermingled with expressions. Alas, a world in confusion is a world true to Perl, no? Perhaps devious Perl Gods make things difficult in order to restrain the instincts of us lesser beings.

Jokes aside, I really don't know, sorry. My mastery of post-modern Perl regex has yet to arrive, or even, to commence.
