Interesting hack but it could actually have been implemented with import and INIT 
package interface;

my %classes;

sub import
{
  my $callerpackage = caller;
  $classes{$callerpackage} = [@_];
}

INIT {
  while (my $class, $info) = each %classes)
  {
    check_a_class($class, $info);
  }
}

To me that seems much cleaner than locks and evals. Especially as the real module forgets to check $@ to see if the code being eval'd died or not.
