The New C++17 Features

In this chapter, we will cover the following recipes:

• Using structured bindings to unpack bundled return values
• Limiting variable scopes to if and switch statements
• Profiting from the new bracket initializer rules
• Letting the constructor automatically deduce the resulting template class type
• Simplifying compile-time decisions with constexpr-if
• Enabling header-only libraries with inline variables
• Implementing handy helper functions with fold expressions
