Indexing into sparse vectors

[karanveerm]

a=spzeros(4, 1);
a[1:2]
ERROR: no method similar(SparseMatrixCSC{Float64,Int64}, Type{Float64}, (Int64,))
 in getindex at abstractarray.jl:364

a[1:3] = 2
ERROR: no method setindex!(SparseMatrixCSC{Float64,Int64}, Int64, UnitRange{Int64})

Now, of course a[1:2, :] works. However, if I can do a=zeros(4, 1); a[1:2], I'd argue the behavior should be consistent for sparse matrices as well.

I'm on Julia Version 0.3.0-prerelease+3461

Should be available now with #7047

julia> a=spzeros(4, 1);

julia> a[1:2]
2x1 sparse matrix with 0 Float64 entries:

julia> a[1:3] = 2
2

julia> a
4x1 sparse matrix with 3 Float64 entries:
    [1, 1]  =  2.0
    [2, 1]  =  2.0
    [3, 1]  =  2.0
