I’m biased since I’m the Fil.

It was materially useful in this project.

- Caught multiple memory safety issues in a nice deterministic way, so designing the object model was easier than it would have been otherwise.

- C++ with accurate GC is a really great programming model. I feel like it speeds me up by 1.5x relative to normal C++, and maybe like 1.2x relative to other GC’d languages (because C++’s APIs are so rich and the lambdas/templates and class system is so mature).

But I’m biased in multiple ways

- I made Fil-C++

- I’ve been programming in C++ for like 35ish years now
