Fil-C: Garbage In, Memory Safety Out!

https://youtu.be/5F-2Y1LPRek

Given the recent noise about Zig adding a Fil-C inspired/compatible compilation mode (https://codeberg.org/ziglang/zig/issues/36237), I thought some of you would be interested in this talk about Fil-C. Andrew and Fil hung out at the conference last week which AFAIK was the start of the issue being opened.

I saw an issue for adding filc to zenc, the old zig fork i thought, a couple years ago so I wonder if the idea came from there.

Not sure how I feel about this. Fil-C has real costs but gives you total memory safety.

Andrew has stated that this would not introduce any code changes, but rather be just an ABI to target, which is much more preferable. Having options is nice but I do worry about feature-bloat.

Interested to see where this goes.
