UFCS as a concept is fantastic but the one hangup is that D's language server implementation by the community and its IDE integration can't handle it because of the complexity. https://github.com/Pure-D/serve-d https://github.com/Pure-D/serve-d https://github.com/Pure-D/code-d https://github.com/Pure-D/code-d (I can't remember if the Visual Studio extension, VisualD handles UFCS or not) http://rainers.github.io/visuald/visuald/StartPage.html http://rainers.github.io/visuald/visuald/StartPage.html It's possible to implement, because Nim's language server handles UFCS, but atm D's doesn't do it (it's written pretty much by one people) So personally I avoid UFCS except for very simple/common function like "to!" because it breaks the intellisense for that call. Though if I knew the language inside and out probably I wouldn't care. It's still my "favorite" language. ----- SIDE NOTE: This single person wrote the D lang server, and has maintained it, written and maintained the VS Code extension, and other fundamental tooling + libs for years. https://github.com/sponsors/WebFreak001 https://github.com/sponsors/WebFreak001 If you use D and feel like sponsoring someone, consider sponsoring them, or Rainers (VisualD), or the maintainers or LDC or GDC, also single individuals for the most part.
