from `perldoc perlvar':
$' The string following whatever was matched by the last success-
ful pattern match (not counting any matches hidden within a
BLOCK or eval() enclosed by the current BLOCK). (Mnemonic: "'"
often follows a quoted string.) Example:
local $_ = 'abcdefghi';
/def/;
print "$`:$&:$'\n"; # prints abc:def:ghi
This variable is read-only and dynamically scoped to the cur-
rent BLOCK.
The use of this variable anywhere in a program imposes a con-
siderable performance penalty on all regular expression
matches. See "BUGS".
