Concepts in 5
summary
Five minute lightning intro to C++ Concepts that shows real syntax and practical limits rather than promises. Demonstrates the requires-requires syntax for expression constraints, the -> return-type placeholder with auto to check result types, and points to GCC builds with -fconcepts for experimentation. Notes that named concepts and abbreviated function template syntax work, that trying to write a concept that accepts another constrained callable is currently impossible, and that Concepts miss C++17 and need more design work.
