People:
I need a way for two collections of different size could be tested for
all elements in both.
A quick and dirty (a prototype) is, to put both into the same new
IdentitySet (or set, depends on your #=) and then just compare sizes.
Then you also don't need to sort, the set (of both) will free you from
sorting. And #copyWithoutAll: can then give you things in B which are not
in A, etc.
HTH.
Example:
A := #(a1 a2 a3).
B := #(b1 b2 b3 b4 b5).
Some similar to
with: otherCollection do: twoArgBlock
"Evaluate twoArgBlock with corresponding elements from this
collection
and otherCollection."
otherCollection size = self size
But for different size
Very thanks
