Lambdas are a common feature of many programming languages. C++ got
lambdas in their C++11 release, many years after D and many other
languages had them. (It is not common for the C++ community to give
credit. Most of their features are presented as C++ inventions when they
are not. For example, almost the entirety of the C++11 features already
existed in D (and other languages before D).)

C++ is the new-kid-in-the-block when it comes to lambdas.
Getting back to lambda syntax, you don't have to use the shorthand =>
syntax. I try to explain how various syntaxes relate to each other:

My book is freely available and I think is better than the documentation
you've shown earlier, which apparently included copies of my text:

You can find most of your questions about keywords and syntax in the
index section:
