Values of arrays changed unexpectedly due to storage allocation issue?

Hope these further discussions & documentations could help other newcomers of Julia like me.

Copy vector?

I just realized this behavior: julia> x = [ 0. , 0. ] 2-element Array{Float64,1}: 0.0 0.0 julia> y = x 2-element Array{Float64,1}: 0.0 0.0 julia> y[1] = 1. 1.0 julia> x 2-element Array{Float64,1}: 1.0 0.0 x and y are just different names for the same vector. How do I copy a vector into another one, then? Also, is there any style suggestion to avoid running into errors given that we could be modifying previous values of array variables this way?
