Approved syntax for C++20 concepts

C++20 has plenty of new features. Between them, concepts are quite useful. I already know that there are some ways on using concepts.

1. By writing requires:

   template<typename T> requires MyConcept<T> // some other stuff
   

2. By using it on the template angle brackets:

   template<MyConcept T>
   // some other stuff
   

However, I know there was another way of writing concepts, which is kinda syntatic sugar. I saw it used on a talk and as I learned later, the syntax was still being discussed because "concept functions are template functions, but the syntax didn't show that". The syntax is like this:

void myFunc(myConcept auto t) // blah blah

My question is, was this syntax approved for C++20?
