I agree, but a precise heap scan should be the easiest part of
this project. Rainer Schuetze has already implemented this and
presented it at a dconf a few years ago(2013?). My plan is to
use that since I know it works, and that frees up my time to
focus on pretty much everything else.
I don't remember all the details, but I'm pretty sure that
Rainer, or maybe someone else, was talking about how a precise
GC is not completely possible in D because D has unions.
I am reading a paper on how one could use extra information about
what was last assigned to a union in order to scan them
precisely. I haven't read the whole thing yet, but it looks like
it could be done.
Not sure if it is something I can get to in the course of my
project though. Scanning only unions conservatively is still
pretty good.
