Hi guys,
I haven't checked if this bug exists already, so please ignore this if it's
been reported before.
Bug in WAMemoryItem:

headerSize := anObject class indexIfCompact 0
ifTrue: [ 4 ]
Hi,
How can I find all objects that reference myObject?

Hi,
Symbol responds to #value:, but not to #value:value:.
At some point, Symbol and Block were decided to have the invocation protocol in
common. I find this great. Therefore, I think, Symbol should also respond to
#value:value:, as follows:
value: anObject value: anotherObject
^
I think it's important to have a consistent answer to the question:
Can you treat symbols as blocks?.

Phexample doesn't duplicate the logic of what is a change method, it changes

Yea, well, it depends on whether we want to be compatible with camp
