Empty Base Class Optimisation, no_unique_address and other C++20 Attributes

Hello,

We invite you to join our next online meeting where we'll be discussing some interesting tricks you can use to make your classes smaller.

The main questions we'll try answering: why unique_ptr can have the size of just one pointer with a stateless deleter?

In the presentation you'll see some internals of STL, what's no_unique_address - a new attribute from C++20. And then we'll also discuss other changes and attributes from C++20.
