For CLI programs Rust is a really nice alternative to languages that require a runtime. I've significantly sped up the time for my bashrc to execute (my bashrc is heavy) by replacing certain tools with Rust tools.

If I wanted my IDE to execute something like ShellCheck on every save, or even every few character presses, I feel like I'd much rather not have to spin up a big runtime.

ShellCheck starts in a few milliseconds on my machine, easily fast enough to run on every character press. Haskell's runtime isn't like the Java JVM, and GHC compiles to machine code, not interpreted bytecode.

Nice, that's impressive.

I really doubt the GHC RTS is appreciably slowing down ShellCheck. Especially if its built with RTS flags optimized for startup. Feels like optimizing the wrong thing a bit.
