Efficient C++ has always been about minimizing copies. This practically-focused
talk is about how to do that when working with move semantics, perfect
forwarding and STL containers, or non-STL containers that present similar

In-place construction is an easily stated goal, but can be really fiddly to get
right, especially given the foibles of various container interfaces. We'll talk
about copy elision; when to use emplace, insert, or other methods; vectors,
maps, optionals, variants; and how things change from C++11 through C++20.
Attendees will learn why in-place construction is beneficial and exactly how to
achieve optimal efficiency with the various standard container types.
