It will solve the following issue of differentiating normalize! with ForwardDiff. It does not make much sense to specify types in a "private" function.

julia> using ForwardDiff: Dual
julia> using LinearAlgebra

julia> normalize!(Dual.(randn(13), randn(13)))
ERROR: MethodError: no method matching __normalize!(::Vector{Dual{Nothing, Float64, 1}}, ::Dual{Nothing, Float64, 1})
Closest candidates are:
