Perl version:

  $Header: perly.c,v 2.0.1.10 88/11/22 01:14:58 lwall Locked $
  Patch level: 18

Using a regular expression in a match pattern seems to destroy the
usability of the "$`" (dollar-leftquote) variable:

 $a = "abcdefghi";
 printf "\$` = %s, \$' = %s\n", $`, $' if $a =~ /def/;
 printf "\$` = %s, \$' = %s\n", $`, $' if $a =~ /d.f/;
 printf "\$` = %s, \$' = %s\n", $`, $' if $a =~ /^abc/;
 printf "\$` = %s, \$' = %s\n", $`, $' if $a =~ /ghi$/;

produces:

 $` = abc, $' = ghi
 $` = , $' = ghi	<== $` should be "abc"
 $` = , $' = defghi	<== could be correct...
 $` = , $' = 		<== $` should be "abcdef"
