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.
- Design note: Postfix operators. Why are unary
*and&postfix? What about++? Why does the->operator naturally disappear? - Design note: Postfix unary operators vs binary operators. What about examples like
a**b? - Design note: Unambiguous parsing. How does Cpp2 parse things that seem ambiguous and/or challenging, like
a<b>c,d>?
