Here’s a short post about two bugs I wrote while writing C++ code for the external scanner of my TLA⁺ tree-sitter grammar. External scanners use handwritten C or C++ code to parse the non-context-free parts of your language. I’ll try not to dump on C++ too hard but both of the bugs are highly ridiculous and exemplify why I hope to write as little of the language as possible for the rest of my career.
