April 2026 — RustPython/RustPython: Exponentiation robustness and error handling enhancements for numeric operations. Key features delivered include enhanced pow() behavior and tests, with CPython-aligned error messages and a dedicated complex power path. Key features delivered: - Exponentiation error handling and robustness improvements: pow() now raises TypeError for non-integer exponents (instead of ValueError); added tests; align error messages with CPython standards; introduced a dedicated complex power function. Major bugs fixed: - pow() type handling regression fixed: corrected ValueError vs TypeError for non-integer exponents and aligned overflow handling for complex exponentiation; added regression tests. Overall impact and accomplishments: - Increased correctness and reliability of numeric operations, improved parity with CPython, and expanded test coverage, enabling more stable numeric workloads and easier maintenance. Technologies/skills demonstrated: - Rust/Python interop in RustPython, CPython compatibility, test-driven development, regression testing, and robust error handling for numeric operations.
