I've had a surprising amount of success asking an LLM to try projects in my toy programming language and report language or tooling issues. Today it noticed that foo(bar,) is syntactically legal but assert(bar,) is not. The parser error is poor in this case too. A real UX bug!

Some excellent safety improvements in C++26: hardening the standard library against out-of-bounds bugs, and a safer semantics for uninitialised local variables:

Chekhov's repro: If a line of code is included in a bug report, it should contribute to the debugging somewhere.
