Chapter 3 (https://github.com/oisee/antique-toy/blob/main/chapters/ch03-demoscene-toolbox/draft.md) does not include some well-known optimizations such as XOR A instead of LD A, 0, or OR A instead of CP 0.
These optimizations are of general use, but they do appear very late in the book (chapter 13), and in a very specific context (Key Techniques at 256 Bytes, https://github.com/oisee/antique-toy/blob/main/chapters/ch13-sizecoding/draft.md#key-techniques-at-256-bytes).
It woule make more sense to have them in the chapter 3, in a Well-known optimizations section, probably before the Bit Tricks: SBC A,A and Friends section.
