Mark,
== tests for object identity. Look for implementors of ==, you find it in ProtoObject:
== anObject "Primitive. Answer whether the receiver and the argument are the same object (have the same object pointer). Do not redefine the message == in any other class! Essential. No Lookup. Do not override in any subclass. See Object documentation whatIsAPrimitive."
<primitive: 110> self primitiveFailed
Cheers

I'm reading "Smalltalk Best Practice Patterns". On page 49 there is this example code.
Object>>= anObject ^self == anObject
I've never seen == in Smalltalk before. It doesn't seem to be a method in Object within Squeak. What's going on here?
