# Module 14: C++26 and the Modern Frontier

## Learning Goals

- Push `constexpr` and `consteval` to compile-time limits
- Chain operations on `std::expected` in a monadic style
- Build expressive ranges pipelines for real data tasks
- Specialize `std::formatter` for domain types (library direction through C++26)

> **Note:** C++26 is still evolving. These exercises use C++23 as the baseline and
> focus on techniques and library directions that remain central in C++26.

## Exercises

| Exercise | Topic |
|----------|-------|
| `constexpr_frontier` | consteval, compile-time algorithms |
| `monadic_expected` | Monadic expected composition |
| `pipeline_ranges` | Advanced ranges pipelines |
| `custom_formatter` | std::formatter specialization |
