<div dir="auto">I am very happy to see this paper. It was an enjoyable read, and accessible to non-experts such as myself. I appreciated the effort spent on research, and was even happier to see that you have started implementing these suggestions and have a plan going forward. Technical debt is a hard thing to overcome, especially in the face of a rapidly evolving language.</div><div dir="auto"><br></div><div dir="auto">This paper resonates with me as both a user and one-time (as in a single time🙂) developer of GHC. As a user, I’ve run into issues related to the debts you discuss.

<br>
With John Ericson and Jeffrey Young we wrote a paper about the <br>
modularization of GHC. It gives a global picture for the refactorings we <br>
have been performing (c.f. e.g. #17957) and some potential future ones.<br>
