Yomm2 VS ffead-cpp

More information about virtual_ptr is available in the documentation.

YOMM2 is available on GitHub.

And if you don't want to put a virtual function or have a base class, etc. check YOMM, which was recently mentioned in r/cpp.

I have a visitor themed example. I will update it to implement the visitor solution as well, for easier comparison.

the main README

I am publishing and documenting some of the internals of my YOMM2 library. I adopted the same style as cppreference.com. My library uses two constructs nested inside a class. cppreference documents template like this and their members like this. However, I use two constructs that are, AFAICT, not used in the standard library, so there is nothing for me to ape.

I don't know much of type theory, i'm just saying that i don't see when this could be useful in real life. On the other hand, multimethods such as what the Julia language has or, in C++, yomm2, sounds much more useful, as you can have two object *a, *b and calling f(a, b) will dispatch on the concrete type of all virtual arguments.

You are partially correct, the framework provides an option to change the backend to any engine (embedded, nginx, apache, picov, rust, c, java, d, js, julia, go, crystal etc), the framework provides integration to all the I/O multiplexing techniques available out there. But I would not reject it plainly with just a single line, more so because "I have built it", whereas for you, you totally have the right to do so, but I would request you to go through the code and also look at areas you may not have browsed earlier and provide any other critical comments you might have missed earlier, that would provide a comprehensive critical review of the framework which will definitely help me improve upon the framework
