Are you going to add solutions to the workshop items to have a go-to when they are stuck or do you accept such solutions? They could for example live in another branch.

I am especially interested in what you mean by:

techniques for compile-time assertions that require type information, by leveraging the trait system in interesting ways from generated code;

In the bitfield macro description.

I keep public reference solutions for all five projects in GitHub if you know where to look, but I wouldn't want them to be listed as branches. I would prefer that people file issues when stuck so that I find out what content needs to be improved.

I really like the test-driven specification by this PR - it gave me a much better understanding of how the interfaces are meant to work towards the user facing side. Maybe I will give it a try. :)

Edit: Don't you intent to publish the bitfield crate to crates.io? I think it is super useful and personally I would prefer it over the alternatives.
