I'm personally surprised it hasn't already happened. It's mentioned by
Larry Wall as the one thing that awk does better, and that was brought up
a long time ago.

If for no other reason than to be able to set $/ to handle all of CR, LF
and CR-LF, it would be worth its weight in gold. One immediate application
of this would be to handling PDF files. Once you've seek'ed to a PDF
object using the internal cross-reference table, it's very natural to read
line by line to actually get the object. Problem being, in PDF allowable
line-ends are precisely CR, LF or CR-LF. If one could just set $/ to a
regexp on all three, life would be much easier. That's just one example.
