推荐答案

来自 Lua 文档第 2.5.9 节，自引用通常是self:

From the Lua documentation section 2.5.9, the self reference is usually self:

冒号语法用于定义方法，即函数有一个隐含的额外参数 self.因此，声明

The colon syntax is used for defining methods, that is, functions that have an implicit extra parameter self. Thus, the statement

function t.a.b.c:f (params) body end

是

t.a.b.c.f = function (self, params) body end
