really wish Rust had variadic generics and named arguments for UI development

Feels like the named args RFC isn’t getting much attention, and variadics are stuck.
After trying different UI kits and both compose- and builder-style APIs, I’ve realized that variadics + named args could cut down a lot on macro DSL usage—Dart does this really well.
But with the current focus on allocators and async traits, I doubt we’ll see these features anytime soon. ：（
