Detailed Description

A C++ lambda expression, which produces a function object (of unspecified type) that can be invoked later.

Example:

void low_pass_filter(std::vector<double> &values, double cutoff) {
values.erase(std::remove_if(values.begin(), values.end(),
[=](double value) { return value > cutoff; });
}

C++11 lambda expressions can capture local variables, either by copying the values of those local variables at the time the function object is constructed (not when it is called!) or by holding a reference to the local variable. These captures can occur either implicitly or can be written explicitly between the square brackets ([...]) that start the lambda expression.

C++1y introduces a new form of "capture" called an init-capture that includes an initializing expression (rather than capturing a variable), and which can never occur implicitly.
