Sorry I could not see wood for the trees!
What is happening is that in MyModule you 'use Cwd',
which EXPORTS 'cwd' by default - so now there is a MyModule::cwd
which is a legitimate over-ride of base class's version so...
You call MyModule->new which inherits from Module->new - so far so good.
But then Module::new calls MyModule->cwd which is the imported one.
So fix is:
package MyModule;
use Module;
use base 'Module';
use Cwd (); # No imports!
Alternatively Module's new could do
sub new {
my $p = shift;
Module->cwd; # ignore override by derived class.
}
But that rather spoils it as a base class.
