What's New in v0.3.0

Added

• Universal iterator support via IteratorView - Accept any Python iterable
  • IteratorView(T) for accepting any iterable (list, tuple, set, generator, range, etc.)
  • Methods: next(), count(), collect(), forEach(), find(), any(), all()
  • Zero-copy: wraps Python iterator directly, no data copying
  • Works with generators, ranges, and custom iterables
• PyIter_Check() and PyObject_IsIterable() Python C API bindings
• Iterator(T) and LazyIterator(T, State) types for returning iterators (placeholder for future)

Fixed

• Use-after-free bug in Path conversion for pathlib.Path objects - Python 3.9 compatibility
  • PyPath_AsString() was decref'ing the string before returning, causing segfaults
  • Added PyPath_AsStringWithRef() to return both string slice and owning PyObject
  • Path struct now stores Python object reference and releases it after function call
  • Proper cleanup in function wrappers ensures no memory leaks

Changed

• Major internal refactoring of class generation - Improved maintainability
  • Split monolithic class.zig (2,887 lines) into 16 modular files
  • New src/lib/class/ directory with protocol-specific modules:
    • mod.zig - Main orchestrator combining all protocols
    • wrapper.zig - PyWrapper struct builder
    • lifecycle.zig - Object lifecycle (new, init, dealloc)
    • number.zig - Number protocol (~700 lines of numeric operations)
    • sequence.zig - Sequence protocol
    • mapping.zig - Mapping protocol
    • comparison.zig - Rich comparison
    • repr.zig - String representation (repr, str, hash)
    • iterator.zig - Iterator protocol (iter, next)
    • buffer.zig - Buffer protocol
    • descriptor.zig - Descriptor protocol
    • attributes.zig - Attribute access (getattr, setattr)
    • callable.zig - Callable protocol (call)
    • properties.zig - Property generation (getters/setters)
    • methods.zig - Method wrappers (instance, static, class)
    • gc.zig - Garbage collection support
  • All comptime generation preserved - no functionality changes
  • Public API unchanged - fully backward compatible
