[LAD] [semi-OT} c++20 concepts and syntax

Hey hey, figuring out the syntax for c++20 concepts I run into challenges. With a two parameter template concept like swappable_with or convertible_to is it always necessary to use a requires statement like this: template<typename T> requires std::convertible_to<T,int> void f(T t) ... ... With single parameter concepts like integral a syntax like this will work: template<std::integral T> void f(T t)... Also with single parameter concepts a statement like this should work: std::integral auto my_variable; Will that work with a two parameter concept like the above convertible_to? I haven't seen/found a syntax which does it. Any help is appreciated, definitely including a good read that WILL demonstrate or demystify these things.
