PerlIO::reverse - Reads lines backward

	open my $rev, '<:reverse', 'foo.txt';
	print while <$rev>; # print contents reversely

The :reverse layer reads lines backward like tac(1).

Here is a minimal implementation of tac(1).

	#!/usr/bin/perl -w
	# Usage: $0 files...
	use open IN => ':reverse';
	print while <>;
	__END__

• This layer cannot deal with unseekable filehandles and layers: tty, :gzip, :dir, etc.
• This layer is partly incompatible with Win32 system. You have to call binmode($fh) before pushing it dynamically.
