Since functions can be passed into functions, that also means that functions can accept another function as an argument. Thefilterfunction assumes its first argument is a function. You can think of thefilterfunction as pretty much the same as this function: deffilter(predicate,iterable):return(it...
Is there a specific reason that you have argument "d" of the actual function to be a pointer (that is also missing in the interface by the way)? I see other pointer arguments as well, probably not needed, especially as they are all intent(in) arguments. You could pass func as an ac...
Of course, parameter Fn must be specialized as, say, template<typename H> function<int(void)> FnInt = H::GetInt; For GetDbl I will have vector<double> vRes, and push_back(H0::GetDbl()) and template <typename H> function<double(void)> FnDbl = H::GetDbl; ...

Arguments in C and C++ language are copied to the program stack at run time, where they are read by the function. These arguments can either be values in their own right, or they can be pointers to areas of memory that contain the data being passed. Pass

This technique often involves some amount of extra work in the function body, such as the move assignment in the example above. If that extra work imposes too much overhead, the slowdown in the cases where the copy can't be elided may not be worth the speedup in the cases where the co...
