Detailed Description

template<typename T>
class std::optional< T >

Minimal header-only polyfill for std::optional for pre-C++17 environments.

This implementation provides the basic interface of std::optional, allowing code to use std::optional<T> and std::nullopt in environments where the standard library version is not available.

Features:

Value storage and lifetime management
Copy/move construction and assignment
has_value(), value(), value_or(), reset(), and conversion to bool
Construction and assignment from std::nullopt

Limitations:

No emplace or in-place construction
No support for references or advanced C++17 features

Usage:

Use as a drop-in replacement for std::optional<T> in C++11/C++14 code
When C++17 or later is available, the standard library version is used
