From Messy to Tidy: A Practical Guide to Writing Clean Kotlin Code
summary
Demonstrates concrete Kotlin fixes: model units to avoid the 20 kg vs 45 lbs bug by using wrapper then value class/inline class so arithmetic compiles to primitives and prevents adding pounds to kilograms; add extension properties (e.g. 20.kg) and operator fun plus returning a new value; warns against overloading unused ops (kg kg → kg²). Recommends characterization tests*, small refactors, dependency inversion and single-function interfaces instead of heavy base interactors.
