Concepts are really amazing. I tried to watch some talks with how metaprogramming worked before concepts and I had to pause a video every 30 seconds. With concepts I didn't even have to pause once. Amazing talk. Thank you so much and to the ones that made concepts possible.

Some abstracts:<br><br>Metaprogramming aims to accomplish a little more in Compile time. One of the solutions for C++ is template and its friends (because template is Turing-complete)..<br><br>The speaker starts with the problem of function template overloading and function template specialization. How to help the compiler determine and choose the suitable template by type becomes the concern of metaprogramming.<br><br>Taking is_container at compile time as an example, he goes from trait, enable-If_t (C++11) + SFINAE + void_t to concepts (C++20) to solve this problem in different ways.<br><br>The final conclusion is that concepts and its library <concepts> are great, and we recommend you use this to check the template type.

So you were saying that my very wide monitor is now no longer needed when debugging c++ compiler messages?
