This proposal would be quite difficult to implement, as it would require an
extension of $/ to regexps.

However, I suggested a different scheme to Perl5-Porters:

 - To introduce an operator -N that would, analogously to -B and -T, scan
   the stdio buffer for the line terminator used in the current file.
 - Adding an implicit $/ = -N; at the beginning of processing of each script.

Reception was less than enthusiastic, but I suppose I will bring it up again
once 5.004 is out the door.
