I did a small comparison of implementing pipeline concurrency in Go and Crystal: https://rillabs.com/posts/crystal-concurrency-easier-syntax-than-golang https://rillabs.com/posts/crystal-concurrency-easier-syntax-... Crystal pretty much provides the same (great) concurrency functionality with light-weight threads and channels etc, but with a cleaner syntax and in my experience less gotchas around closing channels in the wrong place and order etc. The main downsides compared to Go I've seen is: - (As mentioned) Compile times - Far less compelling cross-compilation story
