Param(x) as AbstractArray?

[JeffFessler]

Would it be possible to make Param(x) have a subtype of AbstractArray (when x is)?

julia> x = [1, 2]
2-element Vector{Int64}:
 1
 2

julia> xp = Param(x)
2-element Param{Vector{Int64}}:
 1
 2

julia> supertypes(typeof(xp))
(Param{Vector{Int64}}, AutoGrad.Tracked{Vector{Int64}}, AutoGrad.Value{Vector{Int64}}, Any)

julia> xp isa AbstractArray
false

So currently the Param version xp cannot be passed to any functions that are expecting AbstractArray inputs.

Edit: I guess it's really AutoGrad.Value{Vector{Int64}} that I am wondering if could be a subtype of AA.

I have no objection to this, but I am not quite sure how to do it in practice.
