I'm looking for an efficient way to find out whether two arrays contain same amounts of equal elements (in the == sense), in any order:

foo = {/*some object*/}
bar = {/*some other object*/}

a = [1,2,foo,2,bar,2]
b = [bar,2,2,2,foo,1]

sameElements(a, b) --> true

PS. Note that pretty much every solution in the thread uses === and not == for comparison. This is fine for my needs though.
