Generating Generators
summary
Implements Python‑style generators for Go by static analysis and code generation: the tool gengen takes functions using a fake yield and emits real Go closures plus a state block, labels and gotos, and a genjen build tag with go:generate so generated code compiles separately. It hoists variable declarations to the state struct, converts blocks to labeled jumps, adapts maps/slices/channels, and runs — demo builds a Fibonacci generator that produces correct values.
