std::make_tuple is sometimes a bit funky. For example I imagined that the lines
return {Example{0,0}, Example{1,1}};
return {{0,0}, {1,1}};
would do the same as long as the return value is std::tuple<Example,Example>. However, that is not the case. One calls the move and the other one the copy constructor. So I started to dig a bit deeper and test a bit more.
This repository contains different ways to create tuples and tracks how often which constructor (/destructor) is called.
As long as you are on a typical linux machine with python3 and the python package pyplotlib, you can create a visualisation of the results by simply running CMake followed by make visualize.
