## What it is
A collection of concise descriptions of C++17 language features presented in comparison tables ('Tony Tables'), typically one markdown file per feature. It serves as a quick reference for developers learning what changed in C++17.

## Use cases
- learn what's new in C++17
- quickly compare C++14 vs C++17 syntax
- find examples of structured bindings
- understand std::optional and std::variant usage
- reference for migrating codebase to C++17

## When to choose
- you want concise table-based comparisons of C++17 features
- you need a quick per-feature reference while coding
- you're teaching or onboarding developers to modern C++

## When to avoid
- you need an authoritative or error-free specification
- you want exhaustive coverage of all C++17 changes
- you need a maintained tutorial with active updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: programming-languages, tutorials
- platform: cpp, cross-platform
- tags: cpp17, tony-tables, language-features, reference, structured-bindings, optional, variant, cpp
