Hi I understand that for a vector `a`

```
b = a
```

makes `b`

refer to a

But this is my lack of understanding, why then does varinfo() show that `b`

occupies the same amount of memory as `a`

?

```
julia> a = ones(2)
2-element Array{Float64,1}:
1.0
1.0
julia> b = a
2-element Array{Float64,1}:
1.0
1.0
julia> InteractiveUtils.varinfo()
