defined and exported in one module to a lower level module

You should be aware that the notion of "lower level" doesn't matter for this kind of thing. While there is a hierarchy of namespaces, Perl doesn't automatically do anything with it. Nothing is exported to lower levels by default. Likewise, lower levels do not inherit methods from upper levels. The hierarchy is entirely a convenience for users.

As Joost said, you have to "use" the module at the lower level for it to work. Likewise, for object oriented programming, you have to "use base" or otherwise set the @ISA array.

package My::Class;

sub foo { print "Foo" }

package My::Class::Reversed;

use base qw( My::Class );

sub foo { print reverse "Foo" }
