ComponentArrays vs LabelledArrays

[amrods]

I’ve been a user of ComponentArrays.jl for a while. Just recently discovered LabelledArrays.jl. They strike as very similar. Are there any fundamental differences between them?

Just as example, this is the kind of use for which I employ ComponentArrays:

Parsimonious way to unpack big structs

using your example, it would be using ComponentArrays using UnPack p = ComponentArray(α=0.1, β=0.2, γ=0.3) function f2(x; p=p) @unpack α, β, γ = p return x^(α) + x^(β) + x^(γ) end I also like to organize the parameters inside the ComponentArray, for example: using ComponentArrays using UnPack # full model function model(p; data=data) @unpack p1, p2 = p @unpack data1, data2 = data # component 1 r1 = f1(p1; data=data1) # component 2 r2 = f2(p2; data=data…

Are there any advantages of LabelledArrays over ComponentArrays in that case?

ComponentArrays.jl is probably just better at this point.
