After a bit of close reading of the docs and source, the following seems to 
work:

   # Create the (anonymous) class based on resultset $rs as
   # $class = $namespace . "::" . $name

   my $schema = $rs->result_source->schema;

   $schema->load_classes( { $namespace => [ $name ] } );

   return $schema->source( $class )->resultset

Is that all there is?

Ok, there are some complication, such as the table name to use, and the base 
class.

Do I really need to register it, or can I get away with returning a 
resultset from the result_source_instance, especilly if I want to use it 
anonymously?
