Perl doesn't do interface checking at compile time; so if you wanted to check it, you'd have to write your own checking code: 
  package Foo;
  use base 'Bar';

  my @missing_methods = grep { ! Foo->can($_) }
    qw(foo bar baz);

  if (@missing_methods)
  {
    die "missing methods: @missing_methods";
  }
