Learning Functional Programming in Go

Solve lack of generics with metaprogramming

Metaprogramming (MP) is about writing code that writes code. In MP, we write programs that treat programs, even themselves, as input data. Our MP will read, analyze, transform, and generate code.

Maybe we can use MP to fix what's missing in Go due to its lack of support for generics?

Maybe. First, let's get a better understanding of what MP is about.

Here are some examples:

• Lexers, parsers, interpreters, and compilers
• Domain-Specific Languages (DSLs)
• Aspect-Oriented Programming (AOP)
• Attributes (.NET)
• Annotations (Java)
• Generics (.NET, Java)
• Templates (C++)
• Macros (C)
• method_missing (Ruby)
• Reflection (Go, C#, Ruby)

There are several types of MP.

Programs that support the eval function can generate ...
