Functional Classes in Clojure
Classes in functional programming are named abstractions with cohesive functions operating on internal data structures, no class keyword needed.

Why TDD and AI coding tools exploit the same psychological flaws
Drew DeVault draws a provocative parallel between Test-Driven Development cults and GenAI adoption, arguing both exploit developers' psychological need to feel competent while potentially undermining actual code quality.
- TDD's hidden influence on architecture: While ensuring test coverage, TDD shapes codebases to be "testable" rather than well-designed, and provides no guarantee that passing tests verify the right behavior for actual user needs.
- The dopamine trap of development metrics: Both TDD's green test suites and AI's rapid output create addictive feedback loops through coverage percentages, CI badges, and productivity metrics that make developers feel competent regardless of actual code quality.
- AI coding agents as the new performance theater: GenAI tools let mediocre programmers experience the rush of 10x developer productivity, building "cathedrals" quickly that have beautiful test coverage but rotten foundations underneath.
- The psychological cost of shortcuts: Developers chase these tools despite knowing the externalities (environmental costs, job displacement) because the feeling of finally being "great" at programming overrides long-term concerns.

Functional Classes
Functional programs should be subdivided into classes (cohesive functions operating on data) just like OO programs—the paradigms are compatible.
