Bjarne Stroustrup: C++ Concepts - Constraints on Template Parameters

Summary

The discussion centers on C++ 20 concepts, a feature that imposes constraints on template parameters for generic components like sort functions. Introduced by Gabby, raised true, and implemented by Andres Arden, this standard library element is now widely available in major compilers such as Clang and GCC, with Microsoft also expected to support it. The practical takeaway is that developers can now leverage these compile-time predicates to define and verify that passed types meet specific requirements, ensuring greater code safety and clarity.
