How to make a fast dynamic language interpreter | Hacker News

The author says a memory-safety tool helped them find bugs deterministically while building a dynamic language interpreter.

That made object-model design easier and sped up debugging during development.

They also argue that C++ with accurate garbage collection can be faster to develop with than standard C++, and in some cases some GC languages.

The takeaway is that tooling and runtime memory-management choices can significantly improve productivity and reduce bugs in interpreter work.
