the lack of generics, so he choose java... good choice, except that:Java is
just doing type erasure!!!
He can simply declare a stub interface in Go and implement this interface in
all his 6 data types. Then write his generic functions only on this
interface, that is all java did. |

是这样吗？

发帖数: 1136 | 8 没怎么写过go, 懒得去查语法了,给个C++里面class例子好了:
class baseT{}; //class is just a dumb interface
class Linklist{
baseT* payload;
Linklist* next;
};
这样任何实现了baseT都能被与Linklist有关的函数操作了. 在Go里做个stub
interface就和这里的baseT是一个意思.
这个等价于C++模板里面做出的linklist container.

发帖数: 5247 | 9 这个人谴责Go没有generics, 他就得maintain multiple implementations of similar
things and ultimately led him to rewrite it all in Java because of the
overhead in maintaining the different-but-similar things and backporting
features between those different implementations.
是他不会用interface还是他在搞笑?
而且他的整个程序没有用channel......让他给代码出来帮他profile他说IP issue不能
给...
