You can get this effect by creating an array of the two objects (rather
than of their components, which doesn't make much sense anyway):
julia> type MyType
a::Float64
b::Float64
end
julia> x = MyType(1, 2)
MyType(1.0,2.0)
julia> y = MyType(3, 4)
MyType(3.0,4.0)
julia> z = [x, y]
2-element Array{MyType,1}:
MyType(1.0,2.0)
MyType(3.0,4.0)
julia> x.a = 10
10.0
julia> z
2-element Array{MyType,1}:
MyType(10.0,2.0)
MyType(3.0,4.0)
