Building a small Language with Go for fun
summary
Builds a tiny language to add union (sum) types to Go and implements a handwritten top‑down parser (starts from an EBNF attempt and then throws it away) that tokenizes with go/scanner, emits go/ast nodes, and runs the standard go/types checker. Generates Go source, injects imports and helper structs to represent unions, runs the generated code, and uses static analysis on the produced AST to enforce constraints — a working end‑to‑end pipeline.
