I don't see the point. What makes you want to do this?
And if you are changing it, why not make it return the list of matches
in a list context?
$last = (index $string, $substring)[-1]
(These type of translations/idioms might be candidates for optimization.)

PRL> =head1 DESCRIPTION
PRL> At present C<index> only returns the index of the first occurrence of a
PRL> specified substring. It is proposed that C<index> take a fourth parameter
PRL> telling it which occurrence of a specified substring to locate:
PRL> $first = index $string, $substring, 0, 1; # first occurrence
PRL> $first = index $string, $substring, 0, 2; # second occurrence
PRL> $first = index $string, $substring, 0, 3; # third occurrence
PRL> If omitted, this fourth parameter would default to 1, thus preversing
PRL> the current behaviour.
PRL> The C<rindex> function would be unnecessary, being replaced by:
PRL> $last = index $string, $substring, -1, -1; # last occurence
