 =head2 What good is C<\G> in a regular expression?
 
-The notation C<\G> is used in a match or substitution in conjunction the
-C</g> modifier (and ignored if there's no C</g>) to anchor the regular
-expression to the point just past where the last match occurred, i.e. the
-pos() point.  A failed match resets the position of C<\G> unless the
-C</c> modifier is in effect.

+C<\A>, which matches at the beginning of the string.
 
 For example, suppose you had a line of text quoted in standard mail
 and Usenet notation, (that is, with leading C<< > >> characters), and
