Oh! I hadn’t noticed [that part of the documentation](https://mauro3.github.io/Parameters.jl/v0.9/manual.html#The-type-specific-(un)pack-macros-(somewhat-dangerous)-1)! Thank you very much.

(What I’m having a little trouble with is [about the compatibility of `Parameters.@with_kw` and ConcreteStructs.jl](https://github.com/jonniedie/ConcreteStructs.jl/issues/4). ([[ANN] ConcreteStructs.jl](https://discourse.julialang.org/t/ann-concretestructs-jl-cut-the-boilerplate-when-concretely-parameterizing-structs/47274))
