[julia-users] Strange type behaviour when creating an array from a slice of another array

[Carlos Baptista]

If I do this:

A = rand(10, 10)
x = A[:, 3]

then typeof(x) is Array{Float64, 1}. However if I do this:

A = rand(10, 10)
x = A[:, 3:3]

then typeof(x) is Array{Float64, 2}.

Is this a bug, or is this behaviour the intention of the developers? In 
case of the latter: why?
