Class joining bug/undocumented feature

[WhiteDragon]

This is the code I am executing:

-whitedragon_system

PHP Code:

new TStaticVar("Movement").join("whitedragon_system_movement");
new Movement("NormalMovement").join("whitedragon_system_movement_normal");
this.movement = new NormalMovement().construct(); 


whitedragon_system_movement

PHP Code:

public function construct() {
  echo("----------");
  echo(this.joinedclasses);
  echo(this.getfunctions());
  for(f : this.getfunctions())
    echo(f SPC f.scope);
  echo("----------");
  return this;
} 


whitedragon_system_movement_normal

PHP Code:

public function construct() {
  echo("movement_normal");
  return this;
} 


The code that you see in whitedragon_system_movement is some debugging code to see exactly what functions exist and what is getting over written.

I get the following output:

That's handful, so I'll sum it up for you:

• echo(this.getfunctions()) echos "construct" twice.
• The loop echos "construct" once.
• It doesn't finish the block of code (there are no ending dashes echoed).

This behavior is getting so weird, I had no idea what was going on.
Even speculation would be helpful.

Thank you.
