Hi Vladimir,
I pulled the latest version of the book bcause the final version came out. I went looking at the table of contents and found one of the sections missing. The section was labelled as “Optimizations” (In the last pdf - it was listed under Part 2 as section 9).
I also checked the github tree and found that there at least one thing that would have been part of that section:
- Constant Folding
I wondered if you just forgot to put that in - or if this was on purpose as a “exercise” for people reading the book.
