Is duplication really a problem in this case? I don't think so. Since
you do, I'm curious what you think the risks are?
I do think it could be more readable though.
occurrencesOf: anObject
"Answer how many of the receiver's elements are equal to anObject."
^ self count: [:each | each = anObject]
Thanks,
Zulq.
