Multiple and Predicative Dispatch
summary
A Python library called Nosis dispatch implements multiple and predicative dispatch, letting the same function name have many implementations chosen by argument types and boolean predicates (e.g., place.ISO3 == 'PH'). Example namespace reports 16 functions bound to 1,348 implementations; demographic queries route to a Philippine API, a Malaysian DB, or a specified source object depending on signature. Numeric examples choose different primality algorithms by integer range. Code and working examples live on the project GitHub.
