Concepts are the heaviest addition, and are really a paradigm shift.
Indeed, but once you get the hang of it it becomes easier.
I have lots of practical examples.
Really exciting. It's all got to do with deciding at which (meta) level to define and subsequently, use "things".

C++:
// Interface contract specification
template<typename T>
concept IInput = requires (T x) { x.message(); };
template<typename T>
concept IOutput = requires (T x, const std::string& s) { x.print(s); };
// I/O stuff
template <typename I, typename O> requires IInput<I> && IOutput<O>
class SUD
{ // System under discussion, using composition
private:
I i; O o;
public:
SUD(const I& input, const O& output) : i(input), o(output) {}
void run()
{ o.print(i.message()); }
};
