Why Go Rocks for Building a Lua Interpreter

Building a Lua interpreter in Go

Freezing prevents unintentional global state and permits sharing Lua data values among concurrent lua.State interpreters without copying. As we can see, the bytecode approach results in fine-grained instructions that the interpreter can process one-at-a-time with short snippets of Go that operate on our value data types. In practice, being able to see at a glance which Lua API calls can produce errors is convenient for maintenance, much like in any Go application, so the benefits outweighed the implementation complexity.
