For July we will have online meetup together with C++ Usergroup Karlsruhe. Rainer Grimm will give us his introduction to C++20 Concepts.

Teaser:

The key idea of generic programming with templates is it to define functions and classes which can be used with various types. Often it happens that you instantiate a template with the wrong type. The result is typically a few pages of cryptic error messages. This sad story ends with concepts. Concepts empower you to write requirements for your templates which can be checked by the compiler. Concepts revolutionize the way we think about and write generic code.
