Wow they actually did it! Congratulations and welcome to the age of second-gen systems languages!
Seems one of the main reasons is to use Rust’s thread safety to enable “concurrent mode”. Anyone with the knowledge able to explain what advantages that would yield for an end fish user?
End user shouldn’t care what PL the software is written in. Their advantages and disadvantages are meaningful for developers only.
PL can have a large impact on features, bugs, bug reports, troubleshooting, performance and documentation. Particularly when dev resources are limited.
It’s hard to see how this opinion holds any water.
Rust is a great choice for a shell built as an interactive shell that doesn’t have to be core to the OS. Over C++ this also makes development more accessible to young programmers.
