Event Loop Reinitialization

I would like to refer to Fi sometimes — function template ARGS_COUNT. Tension: instead of bloating function definition with std::floating_point auto and decltypeing after. Outcome: It is possible to provide a more succinct "skeleton" by using auto for parameters types. | I would like to define a macro that would take number of arguments in function template ARGS_COUNT — If it's possible, I would like to define a macro. Tension: I want this, since I would like to refer to Fi sometimes, instead of bloating function definition. | Instead, you could define a functor foo like this — If the goal is mainly to process some type checkings on your parameters. Tension: without macros. Outcome: Then, you can define a structure (say CommonFloatChecker) that encapsulates a generic functor Fct and makes the required checkings at compile time.
