13. Generics Programming
14. "Dynamic, highly parameterized software is harder to understand and build than more static software." (Gang of Four 1995:21)
15. Generics are a trade off between programmer time, compilation time, and execution time. See https://github.com/golang/proposal/blob/master/design/15292-generics.md

17. Code Generation
18. JSON Hyper Schema + HTTP Request
19. JSON Hyper Schema Swagger prmd
20. HTTP Request Alamofire APIKit
21. Code Generation • Demo (If enough time to introduce) • https://github.com/kaneshin/genkit (golang, ver. 0.0.1) • JSON Hyper Schema - prmd • HTTP Request - APIKit
