This is quite useful! Thanks for writing it down. A few points:

It might be nice if it defined HPT and EPS a bit more concretely (at
least expand the acronyms, ideally including a bit of text defining
their roles in the compiler and why there is two of them).

You say "we produce TyCons and another type checking entities for them".
Should this read "other type checking entities for them"?

Otherwise it looks good to me.

Cheers,

- Ben
