About code. Mostly on C++
In the beginning, there was const. And people saw that const was good. And then the people said: let there be constexpr, and consteval, and constinit. And thus, starts this article about constant functions and variables in C++20, which I will try to keep short and concise.
The C++ community has worked hard in the past decade and more to move the language forward, to enrich but also simplify it, and to adopt new paradigms and coding styles. Yet, a single topic, a simple matter of style is splitting the community, in a pure Swiftian manner: the use of the const qualifier that some prefer it on the left of what it modifies, as it has been the de facto standard for decades, and which is now called West const, or to the right of that it modifies, that is a style that more and more people are adopting, and which is now called East const. I don’t particularly like this terms, I would rather use left const and right const, but if this is what the community prefers to use let’s call them so for consistency.
