C++20 is finally here and with it the feature that was long time
coming -- concepts.
This talk will cover what concepts conceptually are (pun intended),
how they fit into the rest of C++, the requires syntax and a few
caveats of using them.
Some people deem concepts a huge and important addition to C++
while some consider them unnecessary because most features they
provide can be simulated with the detection idiom. Let's see
in which group you will be after this talk.
