Go "this"-keyword
问题
在深入研究文档后，我找不到对我以下问题的答案：
在下面的示例中，使用this来引用当前对象是否有任何理由？
type MyStruct struct {
someField string
}
func (this MyStruct) getSomeField() string {
return this.someField
}
英文:
After diving into the docs I couldn't find the answer to my following question:
Is there any reason against using this for referring to the current object as in the following example?
type MyStruct struct {
someField string
}
func (this MyStruct) getSomeField() string {
return this.someField
}

没有技术上的理由不这样做。
这确实违反了通用指南，如这里所解释的：
> 不要使用诸如“me”、“this”或“self”之类的通用名称，这些标识符是面向对象语言的典型特征，更强调方法而不是函数。
我还想补充一点，在使用this（或self）的语言中，this始终是一个指针。对于Go中的方法接收者，情况并非总是如此。
英文:
There is no technical reason not to do this.
It does go against the general guidelines as explained here:
> Don't use generic names such as "me", "this" or "self", identifiers typical of object-oriented languages that place more emphasis on methods as opposed to functions.
I would also like to add that in languages that use this (or self), this is always a pointer. For method receivers in Go, this is not necessarily the case.
