Dan,
The stack effect specifies ( args... receiver selector -- )
>> ALIEN: 200390416
>> B{ 0 0 128 63 0 0 0 64 0 0 202 66 0 0 204 ~1 more~ }
>> "foo:"
What I see on the stack is
receiver
arg
selector
Am I missing something?
ALIEN represents an instance of Foo and it's what we are sending the
message to so it's the receiver.
Thanks, Joel
