Weekend update: Operator and parsing design notes

Thanks again for all the bug reports and feedback for Cpp2 and cppfront! As I mentioned last weekend, I’ve started a wiki with “Design notes” about specific aspects of the design to answer why I’ve made them they way they currently are… basic rationale, alternatives considered, in a nutshell, as quick answers to common questions I encounter repeatedly.

This weekend I wrote up three more short design notes, the first of which is the writeup on “why postfix unary operators?” that I promised in my CppCon 2022 talk.
