More Lambda Features with C++20
by Rainer Grimm
From the article:
Lambdas in C++20 can be default-constructed and support copy-assignment when they have no state. Lambdas can be used in unevaluated contexts. Additionally, they detect when you implicitly copy the this pointer. This means a significant cause of undefined-behavior with lambdas is gone...

by Kate Gregory
From the article:
At the start of the lockdown, Pluralsight made its huge curriculum free to help those who were suddenly needing new skills to find a new job during the pandemic.

C++ Lambda Week: Going Generic
by Bartlomiej Filipek
From the article:
We’re in the third day of the lambda week. So far, you’ve learned basic syntax and how to capture things. Another important aspect is that lambdas can also be used in the “generic” scenarios. This is especially possible since C++14 where we got generic lambdas (auto arguments), and then in C++20, you can even specify a template lambda!
