Why use reflected methods like __radd__?

Reflected methods allow your custom objects to handle operations when they are on the right side of an operator, such as ensuring '5 + my_object' works the same as 'my_object + 5'.

What is a Python DSL?

A Domain-Specific Language (DSL) in Python is a specialized syntax created using native language features to solve problems in a specific field, like math, physics, or database querying.

Is this suitable for production query builders?

Yes, many popular libraries like SQLAlchemy and Django's ORM use similar operator overloading patterns to build safe and expressive query interfaces.

How does this help with AI coding?

Data Science & ML

Enables the creation of expressive domain-specific languages in Python by overloading arithmetic and logical operators.

This skill provides Claude with the expertise to implement the Norvig pattern for operator overloading, allowing developers to create internal DSLs where code matches mathematical or domain-specific notation. It guides the implementation of magic methods like __add__ and __rmul__ to build complex expression structures rather than performing immediate calculations, making it ideal for symbolic math, query builders, and fluent API design.

Key Features

01Implements arithmetic magic methods for structural expression building

021 GitHub stars

03Configures structural equality and hashing for logic-based data structures

04Provides patterns for immutable, non-mutating operator behaviors

05Generates readable string representations for complex expression trees

06Handles reflected operators for natural syntax like '2 * x'

Use Cases

01Creating a fluent SQL query builder using Pythonic operators

02Developing matrix or vector libraries with intuitive mathematical syntax

03Building a symbolic math engine for algebraic manipulation
