That sounds really nice. I have a couple of Haskell servers running on VMs, but the build requirements really slow down the process. I have to use dockers to help cache dependencies and avoid recompiling things that have not changed, but it is still slow and puts out large binaries.
The idea of having a language with most the batteries for a web server built-in is nice. I've never considered Golang, but it is compelling. I'll have to check it out. Though Rust keeps catching my eyes.
