Thank you very much for the link ! The conciseness of the C function build looks like blackmagic 😮 I should add this one to [Sum performance for Array{Float64,2} elements - #14 by LaurentPlagne](https://discourse.julialang.org/t/sum-performance-for-array-float64-2-elements/10873/14) benchmark curves (I think I remember that gcc did not perform very well on that specific loop).
