Your optional(s), and how you use them!

This section will ask about various kinds of optionals you may use, and how you might use them. They will also talk about references, rebinding, and assign/assign-through. If you do not understand this terminology, simply pick to the best of your ability and then answer the questions below the check boxes that indicate your level of knowledge! You're also free to go out into the wild or ask around about what the terms may mean. If you would like a quick read (this one is trying to sell a point, but it still overviews the landscape nicely), see: https://tristanbrindle.com/posts/optional-references
