I'd tried that initially as:

public function __get( $class ) {
   if(array_key_exists( $class, $this->relationships )) {
     if( $this->relationships[ $class ] == 'has_a') {
       $this->$class  = new $class( $this->id );
       return $this->$class;
     }
   }
}

called from:

$sales_order = new sales_order( 1 );
$sales_order->has_a( 'customer' );
print $sales_order->customer->address1;

results in no output being generated. Using a suggestion of Todd Ruth's:

public function __get( $class ) {
   if(array_key_exists( $class, $this->relationships )) {
     if( $this->relationships[ $class ] == 'has_a') {
       $value = $this->$class  = new $class( $this->id );
       return $value;
     }
   }
}

and then running that same print code from above results in:

  123 maple street

being generated. Which is the test data that I have for the customer 
table associated with the sales_order with primary id of 1. Weird, huh?
