Is this expected hashing behaviour?

julia> a = [rand(0:1, 200) for i in 1:10000]
julia> b = deepcopy(a)
julia> a[1][1] = 2
julia> hash(a) == hash(b)
true

It seems to be different with smaller vectors:

julia> a = [rand(0:1, 200) for i in 1:10]
julia> b = deepcopy(a)
julia> a[1][1] = 2
julia> hash(a) == hash(b)
false

From Slack:

From the hash(A::AbstractArray, h::UInt) function:

    # Goal: Hash approximately log(N) entries with a higher density of hashed elements
    # weighted towards the end and special consideration for repeated values. Colliding
    # hashes will often subsequently be compared by equality -- and equality between arrays

This is done as otherwise hashing of arrays would always be 0(n).
