免责声明：我现在只玩了一天Go，所以很有可能我错失了很多。
有人知道为什么会有没有真正的支持泛型/模板/ WhatsInAName在Go？所以有一个通用的 map ，但这是由编译器提供的，而Go程序员不能编写自己的实现。所有关于使Go尽可能正交的讨论，为什么我可以使用泛型类型但不创建新类型？
特别是当涉及函数式编程时，那里是lambdas，甚至是闭包，但是对于缺乏泛型的静态类型系统，我该如何编写泛型高阶函数，如 filter（predicate，list）？ OK，链接列表等可以通过 interface {} 牺牲类型安全来完成。
在SO / Google上没有透露任何见解，它看起来像泛型一样，如果有的话，将作为事后补充加入Go。我确信汤普森比爪哇人做得更好，但为什么要把泛型放在外面？或者他们是否计划并且尚未实施？ 解决方案

Disclaimer: I've only played with Go for one day now, so there's a good chance I've missed a lot.
Does anybody know why there is no real support for generics/templates/whatsInAName in Go? So there is a generic map, but that's supplied by the compiler, while a Go programmer can't write her own implementation. With all the talk about making Go as orthogonal as possible, why can I USE a generic type but not CREATE a new one?
Especially when it comes to functional programming, there are lambdas, even closures, but with a static type system lacking generics, how do I write, well, generic higher order functions like filter(predicate, list)? OK, Linked lists and the like can be done with interface{} sacrificing type safety.
As a quick search on SO / Google did not reveal any insights, it looks like generics, if at all, will be added to Go as an afterthought. I do trust Thompson to do way better than the Java guys, but why keep generics out? Or are they planned and just not implemented yet?
