Is there a null IOStream?

[K Leo]

At times I don't want to output anything, so I pass a null IOStream to a
function that requires an IOStream. How to do that?

[Matt Bauman]

It'd be nice if the DevNull object (http://docs.julialang.org/en/latest/stdlib/base/#Base.DevNull) would work for this, but it seems like it only works for command redirection right now:

julia> run(`echo "Hello"` |> DevNull)

julia> print(DevNull, "Hello")

ERROR: type DevNullStream has no field status

Even if I could check something like the following is better:

isopen(DevNull)

cc:ing Keno and Jameson as the authors of DevNull.

I don't see a good reason for DevNull not to behave like this.
