C++ has always had a powerful meta-programming sub-language which allowed library developers to perform magical feats like static introspection to achieve polymorhpic execution without inheritance. The problem was that the syntax was awkward and unnecessarily verbose which made learning meta-programming a daunting task.

With the recent improvements to the standard, and with the features planned for C++20, meta-programming has become much easier, and meta-programs became easier to understand and reason about.

In this talk, we will present a few modern techniques of meta-programming, with main focus on the magical void_t meta-function and concepts simulation using the detection idiom.
