The way a domain is constructed from a set is currently inconsistent:
julia> s = Set([ [2,3], [4,5]])
Set(Array{Int64,1}[[2, 3], [4, 5]])
julia> d = Domain(s)
a union of 2 domains:
1. : DomainSets.WrappedDomain{Array{Int64,1},Int64}([2, 3])
2. : DomainSets.WrappedDomain{Array{Int64,1},Int64}([4, 5])
julia> 2 ∈ d
true
julia> 2 ∈ s
false
julia> [2,3] ∈ s
true
julia> [2,3] ∈ d
ERROR: MethodError: Cannot `convert` an object of type Array{Int64,1} to an object of type Int64
It seems safer to wrap a set into a wrapped domain as a whole, rather than to make a union of wrapped domains out of it. An alternative is to wrap each element of a set into a Point domain.
