ENTER reviewer's notes:
There are interesting technical details and surprising conclusions that virtual
functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep assembly %r12 result ^= b->concrete();12e3: e8 a8 ff ff ff call 1290 <Base::virt() const>12e8: 41 31

Conclusion
## Preface
The C Handbook follows the 80/20 rule: learn in 20% of the time the 80% of a topic.
In particular, the goal is to get get you up to speed quickly with C.
This book is written by Flavio. I publish programming tutorials on my blog flaviocopes.com and I organize a yearly bootcamp at bootcamp.dev.
You can reach me on Twitter Twitter @flaviocopes.
Enjoy!

## BEN DEANE / @ben_deane
CPPCON 2021
## I N THIS TALK
1. Composability defined
2. Composable types right."
-- Andrei Alexandrescu (CppCon 2015)
As for allocators, so for everything.
## PART 1: FUNCTIONS
## Starting at the bottom and working our way up:
Function-level composability
## THE RETURN TYPE loops, really
• a lot of caching schemes (or idempotent calculations)
• polling/non-blocking functions
## bool UNDERLIES SO MUCH
It seems so trivial that we often don't notice it.
