There are 2 repositories under higher-kinded-types topic.
C# functional language extensions - a base class library for functional programming
Functional companion to Kotlin's Compiler
A type-level library enabling the creation and the manipulation of type constructors which can be detached from their type parameters. Also referred to as higher kinded types.
Some examples for Λrrow Meta the functional companion to Kotlin's Compiler & IDE.
Fωμ type checker and compiler
A proc macro for real async traits, using nightly-only existential types and generic associated types to work around the need for type erasure
Over-Complicated Database Query using higher-kinded data
Experiments with higher-kinded types and object algebras in C#
Experimental HKT framework and generic traits for the standard library
Extract or modify pieces of arbitrarily nested types with type lenses
A refined implementation of Lightweighted Higher Kinded Types in Julia(via typeclasses/traits)
A statically typed functional programming inspired by Haskell, OCaml and Rust.
A static-land and fantasy-land compliant library containing interfaces for common type-classes and common instances of them.
Lambe compiler
Pratical functional programming presentation and sample.
Highly experimental TypeScript project providing a type-level lambda.
Exploring ways to encode functional concepts like structural pattern matching, type classes and fixed points in Java.
Non trivial Type Programming in Typescript
Abstract patterns in JS
A pluggable typescript library / 一个可插件化的 TS 库
Some experiments with annotation processors, code generation, higher kinded types (sort of) and typeclasses (sort of) in Kotlin
Explore functional DSLs and type systems in Java and Kotlin that facilitate easier-to-read, cleaner, more testable, and more fault tolerant code
