I think this comment is referencing the fact that as of right now, slicing a julia array creates a copy and not a lightweight "view" of the sliced data. This makes vectorized operations on slices of arrays sometimes faster in numpy than in julia. See https://github.com/JuliaLang/julia/issues/3701.

Note that you already can make view slices, it just isn't the default. As per the issue you linked to, the default will change to views in version 0.3.
