Next year is 2018 and next C++ is 20. How quaint.

P0618RO: “…The entire header <codecvt> (which does not contain the class codecvt!) is deprecated, as are the utilities wstring_convert and wbuffer_convert. These features are hard to use correctly, and there are doubts about whether they are even specified correctly. Users should use dedicated text-processing libraries instead…”
(In a rush? For the comprehensive “all in one” solution please goto here )
Therefore: C++17:codecvt is, officially, irrevocably, gone. For good. Deprecated. And there is this highly suspicious: “Text-processing libraries” advice. Panic? Please don’t. My advice? “Stay cool calm and collected and all things will fall into place”. Read on. Continue reading
[Note: metacall base article]
I am currently in the stage of searching for simple but valid examples of metacall validity (aka: usefulness) as interfacing concept and programming idiom.
And, I think I have found one. metacall + project Euler. The mathematical nature of some computational problems make them a great fit for the functional paradigm. For those of you who don’t know, “Project Euler is a series of challenging mathematical/computer programming problems…” (ProjectEuler.net). I have concluded I could use the simple and interesting solution for a problem from “Project Euler” to show metacall in action.

Instead of me fantasizing please refer to this actually simple language proposal on what and why is missing and how (very likely) lambdas will look in C++20. Modern C++ lambdas will be even better. Continue reading
This time we go to the Lambda Top Gear. Forget the templates. Use lambdas. Part 3, can actually hurt the brain. If not feeling safe or no chaperone present, please leave now.
Or just jump back to Part 2, simple but useful text. Continue reading
In this post, I have improved the dbj::print() lambda from the part one.
Allow me to analyze it for you in a bit of a detail. First what you like most, the code.
(Alternatively if you feel brave and kind of a clear headed, feel free to snub this beginners text and jump straight to Part 3 )
