flow-runtime: Cannot resolve type: Buffer

This is a:

Bug Report

Which concerns:

flow-runtime

---

What is the current behaviour?

code like:

function foo(): Buffer {
  return getData();
}

produces:

flowRuntime.ref('Buffer')

which results in the warning:

flow-runtime: Cannot resolve type: Buffer

---

What is the expected behaviour?

I would expect it to use Buffer.isBuffer or instanceof Buffer to check that the returned value is a buffer.

---

Which package versions are you using?

0.5.0

[phpnode]

building it now

[phpnode]

hmm, on reflection i wonder if we should fall back to an instanceof check if we don’t have a definition and we can find a global with that name.
