## What it is
refl-cpp is a header-only C++17 library providing static, compile-time reflection and introspection. It encodes type metadata in the type system, enabling constexpr and template metaprogramming over types, fields, functions, attributes, and proxies.

## Use cases
- enumerate struct fields at compile time in C++
- serialize objects generically without code generation
- attach custom attributes to types and members
- build proxy wrappers around types with the same members
- invoke member functions by name at runtime
- write generic code that introspects types via template metaprogramming

## When to choose
- you need compile-time reflection in C++17 with zero dependencies
- you want a small API surface and header-only integration
- you need support for overloaded functions, template types, and custom attributes

## When to avoid
- you need runtime-registered reflection without macros
- your project targets a standard older than C++17
- you need reflection for types you cannot modify to add metadata macros

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools
- domain: developer-tools, programming-languages
- platform: cpp, cross-platform
- tags: reflection, header-only, metaprogramming, compile-time, cpp17, no-dependencies
