I was contacted a few weeks ago by someone interested in my time working on Homestuck. I dumped a huge pile of thoughts and feels, and they wrote an article.

The article understandably is fairly edited, but I spent a bunch of time on my replies, and they're pretty personal, so I felt like archiving my response here. So here's the raw content of the email I sent:

So some disclaimers here: I don't have the best memory, and a lot of the relevant history here is content on the MSPA forums, which as far as I can tell have been completely annihilated from the internet. (a genuine tragedy) Consider everything I say to be suffixed with an "(I think?)" :)

/// `*mut T` but non-zero and covariant.
/// This is often the correct thing to use when building data structures using
/// raw pointers, but is ultimately more dangerous to use because of its additional
/// properties. If you're not sure if you should use `Shared<T>`, just use `*mut T`!
/// Unlike `*mut T`, the pointer must always be non-null, even if the pointer
/// is never dereferenced. This is so that enums may use this forbidden value
/// as a discriminant -- `Option<Shared<T>>` has the same size as `Shared<T>`.
/// However the pointer may still dangle if it isn't dereferenced.
