The following is the text conclusion:
This function template can unify the function type and the object function type (that is, the operator() operator function is defined in the class) into one type. Anyway, they are all callable objects.
There are 900 lines of commented code, which is quite a lot. Choose the most important conclusions and post them.
(1) How does the template receive function objects?
(2) The experimental results are given below
