What's New in v0.7.1

Fixed

  • Cross-class references now work between module classes - When a module defines multiple classes (e.g., Point and Line), methods on one class can now accept or return instances of another class in the same module. Previously, class method wrappers only knew about their own class (or no classes at all), so cross-class conversions would fail with TypeError or SystemError. The fix threads the full class_infos list through the entire class generation pipeline — from generateClass() through every protocol builder (methods, lifecycle, properties, number, sequence, mapping, descriptor, repr, attributes, iterator, callable, comparison) — so every converter sees all sibling classes. Cyclic references (A references B and B references A) work correctly thanks to Zig's comptime memoization.
  • Comparison operators now support cross-class types - __eq__, __ne__, __lt__, __le__, __gt__, __ge__ previously hardcoded the other parameter to be the same type as self. Now the comparison protocol introspects each method's signature and uses the class-aware converter, so __eq__(self: *const A, other: *const B) bool works correctly.
  • __int__, __float__, __index__ now use class-aware converter - These number protocol methods were using the old zero-class Conversions.toPy() instead of the class-aware Conv.toPy(), which would have failed if they returned a custom class type.
  • Class parameters now supported by value and by pointer - Methods can now accept class instances either by pointer (fn foo(p: *const Point)) or by value (fn foo(p: Point)). Previously only pointer parameters worked for cross-class references; by-value parameters would fail with TypeError because the struct branch of fromPy didn't check registered class types.
