Julia 0.6:

```julia
julia> rand(Complex128, 2)
2-element Array{Complex{Float64},1}:
 0.548883+0.127059im
 0.331562+0.484864im

```

Julia master:

```julia
julia> rand(Complex128, 2)
2-element Array{Complex{Float64},1}:
 0.018193872615607898 + 0.49673778988579875im
   0.1193360128323322 + 0.5151124572980095im

```

It seems that in Julia master the `:compact` property is `false` when representing arrays. Is this an intended change?
