Hello,
Some Julia functions act on their inputs. For example:
julia> vals = [6,5,4,3]
4-element Array{Int64,1}:
6
5
4
3
julia> sort!(vals);
julia> vals
4-element Array{Int64,1}:
3
4
5
6
However, it looks like these functions do not modify array slices:
julia> vals = [6,5,4,3]
4-element Array{Int64,1}:
6
5
4
3
julia> sort!(vals[2:end])
3-element Array{Int64,1}:
3
4
5
julia> vals
4-element Array{Int64,1}:
6
5
4
3
Can anyone explain to me why this happens? Is this a language feature? Is
it at all possible to make a destructive function that acts on slices?
Cheers,
Daniel.
