Feature description

Replace all std::bind with lambda. Is it worth doing it for now?

isocpp/CppCoreGuidelines#1796

Implementation considerations

e.g.

Replace

rclcpp/rclcpp/src/rclcpp/time_source.cpp

Lines 130 to 133 in e9e398d

	parameter_subscription_ = rclcpp::AsyncParametersClient::on_parameter_event(
	node_topics_,
	std::bind(&TimeSource::on_parameter_event, this, std::placeholders::_1));
	}

with

  parameter_subscription_ = rclcpp::AsyncParametersClient::on_parameter_event(
    node_topics_,
    [this](std::shared_ptr<const rcl_interfaces::msg::ParameterEvent> event) {
        return on_parameter_event(event);
      }
    );

I'm not opposed to it, but I'm also not sure if it is a really important thing to do either.

A few somewhat unimportant things to consider:

• using std::bind in rclcpp gives us implicit coverage on that use case, which is nice but not required as we have demos that cover that case too
• in the example you gave, std::bind is slightly nicer because we don't need to include the type of event, and don't think auto would work in this case due to how the template deduction works on that

But I don't think those points push me one way or the other that much.
