C++20: Concepts, the Details
by Rainer Grimm
From the article:
In my last post C++20: Two Extremes and the Rescue with Concepts, I gave the first motivation for concepts. Concepts put semantic constraints on template parameters. Today, I present different use-cases for concepts in a compact form...

Named Template Arguments
by Barry Revzin
From the article:
C++, unlike many other programming languages, doesn’t have named function parameters or named function arguments. I hope it will someday, it’s a language feature that I find has large benefits for readability. Until then, in C++20, we actually have the ability to do a decent approximation not only of named function arguments but also named template arguments...
