 To implement a new operator for an existing backend, you need to write 5 methods: 1 for [preparation](@ref Preparation) and 4 corresponding to the variants of the operator (see above).
 For first-order operators, you may also want to support [in-place functions](@ref "Mutation and signatures"), which requires another 5 methods (defined on `f!` instead of `f`).

+The method `prepare_operator_nokwarg` must output a `prep` object of the correct type.
 For instance, `prepare_gradient(strict, f, backend, x)` must return a [`DifferentiationInterface.GradientPrep`](@ref).
 Assuming you don't need any preparation for said operator, you can use the trivial prep that are already defined, like `DifferentiationInterface.NoGradientPrep{SIG}`.
 Otherwise, define a custom struct like `MyGradientPrep{SIG} <: DifferentiationInterface.GradientPrep{SIG}` and put the necessary storage in there.
