'send' and behaviors

[Dar Scott]

There are two problems with that description.  

One is what Mark mentioned.  The default stack will change to the stack of the target object and the default card will be the current card of that the new default stack.

However, there is something else.  The word "message" should be replaced with "handler".  

That is 'this stack' here refers to the stack of the sender:
send "doSomething x, the name of this stack" to card "uno" of stack "beta"

But here in card "uno" it refers to that of the target:

on doSomething x, y
	put the name of this stack
end doSomething

All object references in the message are evaluated in the current context i. e. the defaultStack. Therefore references within the message that refer to "this card" or "this stack" will be referring to the card or stack where the target handler is located.

The handler is however also in a behavior, which has certainly been correctly associated with the target card.
