                CoffeeScript upcoming changes.
              
          
    CoffeeScript 1.7 is shaping up to be a pretty kick-ass release with significant improvements. Here are the ones I'm most excited about, in order of my own excitement.
Parentheses-free chaining

                Comaprison of C and Rust syscalls on startup/shutdown.
              
          
    Abstract

For some situations, understanding system calls made during processes start-up and shut-down can be valuable. For example, consider a shell-scripts long-running hot loop that runs a very short-running process. Thus it is perhaps reasonable to hypothesise that a difference in system calls during process start-up/shut-down has a non-negligable impact on the run time of said hot-loop.
This write-up looks at how C and Rust programs differ in terms of system-calls for start-up/shutdown. It is not intended as a performance analysis and only looks at one target system.
At the end, we take a quick look at using statically linked libraries by building with # cargo build --target x86_64-unknown-linux-musl --release and removing even more syscalls by removing the main function
System
