Introduce Parameter Object
Domain: Refactoring
🎯 Motivation
Functions with many related parameters are error-prone and hard to read. Grouping them into an object clarifies intent, reduces argument count, and makes future additions easier.
📋 Concrete Example
create_order(customer, item, qty, price, address, coupon) becomes create_order(OrderRequest) where OrderRequest bundles the fields. Callers build one clear object instead of six positional args.
🔗 Analogy
Handing a librarian a single “book request form” is easier than shouting six separate details. The form groups everything they need, so nothing gets lost or misordered.
