A quick hack (overwriting the method to ignore the `compact` directive in the `IOContext`):

```julia
<< Base.show(io::IO, x::Union{Float64,Float32}) = Base.Grisu._show(io, x, Base.Grisu.SHORTEST, 0, true, false)
WARNING: Method definition show(IO, Union{Float64, Float32}) in module Grisu at grisu/grisu.jl:120 overwritten in module Main at REPL[0]:1.

<< rand(5)
>> 5-element Array{Float64,1}:
 0.41685881323027596
 0.43774537729371676
