Generic interfaces

Generic interfaces Axel Wagner 7 July 2025 There is an idea that is not obvious until you hear about it for the first time: as interfaces are types themselves, they too can have type parameters. This idea proves to be surprisingly powerful when it comes to expressing constraints on generic functions and types.
