C++11 lambda capture `this` and capture local variables by value

As cppreference says:

[=] captures all automatic variables used in the body of the lambda by copy and current object by reference if exists

[=] does what you want -- it captures anything not a member variable by value, and *this by reference (or this by value).

[*this,=] captures both local variables and the object by value in c++17.

[&] captures local variables by reference and *this by reference or this (the pointer) by value.

Both default capture modes capture this the same way. Only in c++17 can you change that.

[=] already captures this by value. Take a look at the following code live here: http://cpp.sh/87iw6

#include <iostream>
#include <string>

struct A {
    std::string text;

    auto printer() {
        return [=]() {
            std::cout << this->text << "\n";
        };
    }
};

int main() {
    A a;
    auto printer = a.printer();
    a.text = "Hello, world!";

    printer();
}
