C</m> modifier is used, while "^" and "$" will match at every internal line
boundary. To match the actual end of the string, not ignoring newline,
you can use C<\Z(?!\n)>. The C<\G> assertion can be used to mix global
-matches (using C<m//g>) and non-global ones, as described in L<perlop>.
+matches (using C<m//g>) and non-global ones, as described in
+L<perlop/"Regexp Quote-Like Operators">.
+It is also useful when writing C<lex>-like scanners, when you have several
+regexps which you want to match against consequent substrings of your
+string, see the previous reference.
The actual location where C<\G> will match can also be influenced
by using C<pos()> as an lvalue. See L<perlfunc/pos>.
