C.170: If you feel like overloading a lambda, use a generic lambda

C.170: 如果需要重載lambda表達(dá)式，使用泛型lambda表達(dá)式

Reason(原因)

You cannot overload by defining two different lambdas with the same name.

你無(wú)法以為兩個(gè)不同的lambda表達(dá)式取相同名字的方式來(lái)實(shí)現(xiàn)重載。

Example(示例)

void f(int);
void f(double);
auto f = [](char);   // error: cannot overload variable and function

auto g = [](int) { /* ... */ };
auto g = [](double) { /* ... */ };   // error: cannot overload variables

auto h = [](auto) { /* ... */ };   // OK

Enforcement(實(shí)施建議)

The compiler catches the attempt to overload a lambda.
