How about if I want to dynamically specialise on a certain value?

using StaticArrays

function f(n::Int)
    b = rand(SVector{n})
    for i in 1:10000
        b += rand(SVector{n})
    end
    return b
end

function f(_n::Val{n}) where n
    b = rand(SVector{n})
    for i in 1:10000
        b += rand(SVector{n})
    end
    return b
end

g1() = f(rand(4:4))
g2() = f(Val(rand(4:4)))

@time g1()
@time g2()

julia> @time g1();

julia> @time g2();
