REPL can't run (some?) generators with yield in the Civet code

[nicholaides]

Problem exists in the playground and the REPL (npx civet).

This code:

do* yield 1

Correctly compiles to this JavaScript:

(function*(){{ yield 1 }})()

But when run in the REPL, errors like this:

🐱> do* yield 1
... 
REPL2:1
(yield* (function*(){(function*(){{ yield 1 }})()})())
^

Uncaught ReferenceError: yield is not defined
    at REPL2:1:1
    at Script.runInContext (node:vm:149:12)
    at Module.runInContext (node:vm:301:6)
    at REPLServer.eval (/Users/mike/WIP/vite-civet/my-vue-app/node_modules/@danielx/civet/dist/civet:424:23)
    at processTicksAndRejections (node:internal/process/task_queues:105:5)

On the playground it shows the same message, but without the backtrace.

Other code that has the same issue:

// ❌ errors
n := for* item of [1,2,3]
  yield 1
  item

// ✅ works
n := for* item of [1,2,3]
  item
