I suggest you to read the chapter on the Smalltalk model in the Squeak
or pharo by example book
the key is:
when you look for a message you look in the CLASS of the receiver
then its superclasses.
So when you look for new sent to Array you should look in the Array
class superclasses and you will see it contains
Behavior before ProtoObject

need to have a google account.
