While re-reading Clean Architecture for my library notes, one sentence stopped me cold. Robert Martin defines the three programming paradigms, and he defines them backwards from every brochure ever printed:
"Each of the paradigms removes capabilities from the programmer. None of them adds new capabilities." (Clean Architecture, ch. 3)
Read it again. Seventy years of language progress, and the three greatest leaps forward are prohibitions. Nobody ever gave you anything. They confiscated your dangerous toys, one by one, and every confiscation made your code more predictable. Once you see the pattern, you see it everywhere, all the way into the languages of 2026. And it raises a dizzying question: what is left to take away?
1968: the first confiscation
The structured paradigm was born from a Dijkstra letter that became legend, "Go To Statement Considered Harmful". The goto was absolute freedom: jump anywhere in the program, anytime. And that was precisely the problem. Code riddled with gotos cannot be read, only investigated. You cannot reason about a block if anyone can land in it from anywhere.
