Good start.

I have updated the page to separate the source-language design (what the programmer sees) from the implementation.

And I have included boxed sums as well – it would be deeply strange not to do so.

Looks good to me!

I have a draft design for unpacking sum types that I'd like some feedback on. In particular feedback both on:

 * the writing and clarity of the proposal and
 * the proposal itself.
