Obtain multiple components from a ComponentArray

[amrods]

Is there a way to obtain multiple components from a ComponentArray?
something like

using ComponentArrays

ca = ComponentArray(x1 = [1, 2], x2 = [10, 20], x3 = [100, 200])

ca[:x1, :x3]
# would return (ca.x1, ca.x2)

@amrods

using ComponentArrays

ca = ComponentArray(x1 = [1, 2], x2 = [10, 20], x3 = [100, 200])

ca[:x1, :x3]

You can do

julia> getindex.(Ref(ca), (:x1, :x3))
([1, 2], [100, 200])

It is in work, but it’s a somewhat tough problem for reasons I mention here. Until I get it figured out, broadcasting getproperty or getindex like @dpsanders did is the way to go.
