These two snippets should be the same:
package Foo;
sub INC{ print "Foo\n" };
package main;
$x=bless {},Foo;
$x->INC;
sub Foo::INC{ print "Foo\n" };
$x=bless {},Foo;
$x->INC;
Only the latter works. I suggest adding this as a note to the section
in L<perlfunc/require>:

Note that these hooks are also permitted to set the %INC entry
corresponding to the files they have loaded. See L<perlvar/%INC>.
+Also note the use of C<sub Foo::INC>, rather than just C<sub INC>;
+this is necessary due to the enchanted nature of *INC. See
+L<perlvar/Technical Note on the Syntax of Variable Names> for more
+information.
For a yet-more-powerful import facility, see L</use> and L<perlmod>.
