Combine py::enumerate and py::const_enumerate

Full Changelog: 1.5...1.5.1

py2cpp v1.5.1 Release Notes 🎉🚀

Released on November 28, 2025

We're excited to ship py2cpp 1.5.1 – a feature-packed release focused on Python fidelity, modern C++ compatibility, and smoother development experience!

New Features & Enhancements ✨

• Full support for enumerate() on const containers
  You can now safely write for i, v in py::const_enumerate(container) – perfect for range-based for loops without copying!
  Also added py::enumerate() wrapper for non-const cases.

• New const_enumerate() utility (with detailed docs)
  Clean, safe, and zero-overhead enumeration over const iterables and ranges.

• Improved dict and list methods

  • dict::contains(key) now properly noexcept and const-correct
  • Added modern items() → returns view of (key, value) pairs
  • len() now works naturally on py2cpp containers

• Better range support
  Full C++20-compatible range semantics with proper begin()/end() and const iterators.

• Added GEMINI CLI command 🌟
  New py2cpp gemini subcommand for AI-assisted code conversion (experimental but awesome!)

Bug Fixes & Build Improvements 🛠️

• Fixed macOS build by adding -DCMAKE_POLICY_VERSION_MINIMUM=3.5 (Who-dev)
• Fixed sign-conversion warnings on Oct 1 → cleaner builds on modern compilers
• Updated CMake workflows to latest standards
• Bumped project version to 1.5.1 and updated CMakeLists.txt accordingly

Under the Hood 🔧

• Merged enumerate() and const_enumerate() implementations for consistency
• Lots of noexcept additions and const-correctness fixes across containers
• Improved template deduction guides
• Better iterator traits and SFINAE handling

CI/CD

• Added proper doctest and boost.ut test packages
• Modernized xmake.lua config
• Cleaner GitHub Actions workflows
