=item * Discontinuance

In Perl 4 (and versions of Perl 5 before 5.004), C<'\r'> characters in
Perl code were silently allowed, although they could cause (mysterious!)
failures in certain constructs, particularly here documents. Now,
C<'\r'> characters cause an immediate fatal error. (Note​: In this
example, the notation B<\015> represents the incorrect line
ending. Depending upon your text viewer, it will look different.)

  print "foo";\015
  print "bar";

  # perl4 prints​: foobar
  # perl5.003 prints​: foobar
  # perl5.004 dies​: Illegal character \015 (carriage return)
