Yes, it is similar in spirit. It is pretty much the same as the 
C++17 version, but easier to write, especially when you require 
many operators (e.g. "a+b", "a*b" etc). I am not sure if C++20 
concepts bring anything truly new, but easier on the eyes and 
more likely to be used correctly. Which is important. A new 
feature isn't necessarily about making new things possible, 
encouraging correct code is just as important.
