C++Now 2018

We say that interfaces should be easy to use and hard to misuse. But how do we
get there? In this talk I will demonstrate how using declarative techniques in
APIs, functions, and plain old "regular" code can help.

We'll look at what is meant by "declarative style" in C++; explore why
declarative interfaces are desirable and how to construct them; and take an
in-depth look at which features of C++ help us write in a declarative style.

I want to deconstruct C++ a bit, examine what we're doing and what makes the
good parts good, and from that reconstruct some best practices. Many of us are
already writing code following piecemeal modern advice such as "no raw loops",
or "almost always auto", or C++ core guideline recommendations. In many cases,
this advice translates to writing more declarative code; being deliberate about
exploring and using declarative techniques gives us insight we can apply more
widely.
