Summary:In the GopherCon 2021 video episode titled "Generics!", Go Team members Robert Griesemer and Ian Lance Taylor discuss the upcoming release of Go 1. 18 and its support for generic functions and types. They highlight the expressive power that generics bring to the Go programming language and the responsibilities that come with using them effectively. The new features in Go 1. 18 include type parameters, more powerful interface types, and improved type inference. These features eliminate the need for type arguments, making programming with generics in Go more efficient. The update also introduces type constraints, which define valid types for a parameter, and interfaces that define sets of methods. Griesemer and Taylor provide guidance on when and where to use generic features in Go. They suggest starting with functions instead of type parameters and using type parameters for functions that operate on special types without assumptions about element types. They emphasize the flexibility and efficiency of type parameters compared to reflection or interface types, allowing for general-purpose data structures and fully type-checked code. The speakers also discuss the importance of understanding meta types and the use of interfaces as constraints in generic functions. They mention the introduction of syntactic sugar and the use of type parameters with slice types. They also touch upon type inference and its role in deducing type arguments from type parameter constraints. Griesemer and Taylor highlight the need to keep Go code readable, maintainable, and performing well when using generics. They advise using type parameters when multiple types share a common method with the same implementation and using interface types for generic programming and reading data from any value. They mention that reflection can be used in cases where type parameters are not helpful. Overall, the upcoming release of Go 1. 18 with support for generics brings significant expressive power to the language. Griesemer and Taylor provide valuable guidance on how to use generics effectively, emphasizing the importance of choosing the appropriate approach based on the specific requirements of the code.
