With Rakudo 0.7.0-devel r31065 inheritance works as in this
single file​:

  class Dog {
  has $.name is rw;
  method bark() {
  say "$.name says Woof!";
  }
  }

  class Pug is Dog {
  method set_name( $n ) {
  $.name = $n;
  }
  }

  my $pot = Pug.new();
  $pot.set_name( 'Spot' );
  $pot.bark();

But move class Dog { ... } into Dog.pm and import it with
'use Dog;' and Rakudo is like 'Attempt to inherit from
non-existent parent class'.

On 2008-09-16 in #perl6 moritz explains that 'use' happens
(erroneously) at run time whereas it should happen at
compile time, and gives a
workaround 'BEGIN { use Dog; };' that works.

Synopsis 11 topic "Runtime Importation" contrasts 'use' and
'require' in terms of time. This request is to obviate the
workaround.

This bug is like fixed.

Well, kinda. Your example now runs. However, modules using modules then
causes some fun (though I'm not convinced this change has made the
situation worse), and this won't play so nicely with pre-compiled
modules. Those'll want tickets of their own, though, so resolving this
ticket since use has been promoted to happen at runtime now.

Thanks,
