No, this is a pretty contentious issue. A lot of the relevant discussion is in #4774 <https://github.com/JuliaLang/julia/issues/4774>. The one thing everyone agrees on which is going to happen in 0.4 for sure is that slicing will generally create views into the original array rather than copying the data.
