As discussed at https://github.com/SimonDanisch/FixedSizeArrays.jl/issues/159, I rather liked writing `Vec` and `Mat` for small sized arrays in FixedSizeArrays. Perhaps we should try to recover these…
A standrad reduction function like:
``` jl
function simd_sum{T}(x::Vector{T})
s = zero(T)
@simd for i in eachindex(x)
@inbounds s = s + x[i]
end
return s
end
```
which vector…
