src: allow getting Symbols on process.env #9631
Conversation
1aa595e introduced a `throw` for accessing `Symbol` properties of `process.env`. However, this breaks `util.inspect(process)` and things like `Object.prototype.toString.call(process.env)`, so this patch changes the behaviour for the getter to just always return `undefined`.

Calling .SetUndefined() explicitly doesn't hurt but it's not strictly necessary as it's the default return value. We don't call it anywhere else.

@bnoordhuis I think making the return value explicit is more readable here, that’s all. If you prefer, I have no problem dropping it.

Isn't this the C++ equivalent of function() { return undefined; }? I've no strong feelings, but explicit isn't necessarily more readable, IMHO.

Yup.

I agree, but in this instance I think it makes sense.
