So there's this guy you may have heard of called Ryan Fleury who makes the RAD debugger for Epic. The whole thing is made with 278k lines of C and is built as a unity build (all the code is included into one file that is compiled as a single translation unit). On a decent windows machine it takes 1.5 seconds to do a clean compile. This seems like a clear case-study that compilation can be incredibly fast and makes me wonder why other languages like Rust and Swift can't just do something similar to achieve similar speeds.

I guess you can do that, but if for some reason you needed to compile separately, (suppose you sell the system to a third party to a client, and they need to modify module 1, module 2 and the main loop.) It would be pretty trivial to remove some #include "module3.c" lines and add some -o module3 options to the compiler. Right?

I'm not sure what Rust or docker have to do with this basic issue, it just feels like young blood attempting 2020 solutions before exploring 1970 solutions.
