Yes, the language is definitely much more complex than I expected. I’m still getting the hang of some syntax choices like the `with … yield` and the myriad ways of using closures: https://crystal-lang.org/reference/1.3/syntax_and_semantics/blocks_and_procs.html#with-yield https://crystal-lang.org/reference/1.3/syntax_and_semantics/... But I really miss some of Crystal’s features in other languages I work with: 1. Being able to declare union types when ingesting some not-so-normalized data alias UserID = String | Int32 | UUID 2. Macros and meta-programming For example here I have a `storedprop` macro which I can use to define propertied that get saved automatically to a YAML config when they are changed: https://f.lunar.fyi/uRW69B/settings.cr https://f.lunar.fyi/uRW69B/settings.cr class Settings include YAML::Serializable storedprop host : String = "ddcutil-server.local" storedprop port : UInt16 = 3485 end The good thing is you’re not really required to learn this stuff if you don’t want. But they surely can make the language fit to your style better if you invest the time to understand them.
