Deserialization in Julia code blocks can throw an error.

The error I'm seeing is the same one reported in this Julia issue, which I'm pretty sure explains the problem, since Documenter.jl wraps code in anonymous modules, right?

Yes it does.

For a little more context, I'm getting the error below when I change julia to @example MNIST here.

┌ Warning: failed to run `@example` block in src/extended_examples/MNIST/notebook.md:328-331
│ ```@example MNIST
│ mach2 = machine(joinpath(tempdir(), "mnist3.jls"))
│ predict_mode(mach2, images[501:503])

│   exception =

| Yes it does.

Then I'm guessing there so easy workaround or adaptation, apart from not evaluating the block as I am doing here, and we will need to wait on the Julia issue.
