YAEGI, Yet Another Elegant Go Interpreter
summary
A production-focused Go interpreter that runs as an embeddable module with the API interp.New()/i.Eval() and optional exposure of compiled packages via i.Use(stdlib). Claims: fully interoperable with the Go runtime, no default use of unsafe, targets Go 1.12–1.13, open source Apache‑2. Status: alpha, less than 8K LOC, zero external dependencies, backed by Containo.us and used as a plugin engine for traefik. Measured example shows 5–10% overhead vs compiled gzip, concurrency and symbol calls work.
