Crate mathhook_macros 

Code generation macros for MathHook language bindings and expression construction

This crate provides procedural macros to generate Python (PyO3) and Node.js (NAPI) bindings from a single function definition, eliminating code duplication while maintaining zero-cost abstractions.

Also provides procedural macros for mathematical expression and symbol construction.

Supported Function Arities

• Unary: sin(x), cos(x), exp(x)
• Binary: pow(x, y), atan2(y, x)
• Variadic: add(args…), mul(args…)
• Constants: pi(), e()
