How do I send the output of show to a file? I tried the following with several mime types without success.

```
julia> open("file.jl", "w") do io
            show(io, MIME"plain/text", [[1,2],[3,4]])
         end

```

The second argument of `show` must be of type `MIME`, while `MIME"type"` returns the `MIME{Symbol("type")}` type (not an instance of that type). To have an instance of `MIME`, call either `MIME("type")` or `MIME"type"()`:

```julia
show(io, MIME("text/plain"), [[1,2],[3,4]])

```

(also, not “plain/text”).
