No compression with `jldsave`

[cafaxo]

With

jldsave("example1.jld2", compress=ZlibCompressor(); x=zeros(10_000))

I do not get any compression. The following works fine:

jldopen("example2.jld2", "w"; compress = ZlibCompressor()) do f
    f["large_array"] = zeros(10_000)
end

Hm, it could be that the docstring is misleading here... Try jldsave("example1.jld2", ZlibCompressor(); x=zeros(10_000))

(without giving a name for the positional argument)

Yes, the docstring says

  jldsave(filename, compress=false; kwargs...)

It works without the compress=.
