[Moose-dev] Re: is CodeFoo maintained?

Excellent I fixed that and added it to the tests

I kept the functional style of union by creating a new set.

union: aSet "Answer the union of the receiver A and aSet B. The union is defined as { x | x in A or x in B }."

| set | self isEmpty ifTrue: [^aSet copy]. set := Set new. set addAll: aSet. set addAll: self. ^ set

Sequenceable>>union: aSet "Answer the union of the receiver A and aSet B. The union is defined as { x | x in A or x in B }."

| stream set | self isEmpty ifTrue: [^aSet copy ]. stream := (self species new: self size) writeStream. set := Set new. set addAll: aSet. set addAll: self. stream nextPutAll: set. ^stream contents
