Zig and Guile? I'm going to watch this later.
I would love to replace Rust + Python with Zig + Guile, with the latter allowing even tighter integration!

Zig and Guile for fast code and a REPL
Zig is a minimalistic new language that is unapologetically focused on performance, tellingly with a blazingly fast compiler. It is advertised as a replacement for Thompson, Ritchie, and Kernighan's C, but it may even replace C++ in places. Zig uses the C-ABI and does not do garbage collection, so it is ideal for binding against other languages, such as C, Python, Ruby etc. In this talk I will present combining GNU Guile with zig. I'll argue that everyone needs two languages: one for performance and one for quick coding. With Zig and Guile you can use both at the same time and you won't have to fight the Rust borrow checker either. Zig is a minimalistic new language that is unapologetically focused on performance.
