LLMs understand nullability

The last five years have shown us that large language models, like ChatGPT, Claude, and DeepSeek, can write code in many domains, to huge excitement: many claim to be using these models to write entire web servers and apps from scratch. These tools have opened up programming to a whole new class of people who consider…
