Missing useful debug information for Dynamic Import errors

[m-a-r-c-e-l-i-n-o]

Hello there,

Node: v9.10.1
Platform: Darwin MACLTUS44977 15.6.0 Darwin Kernel Version 15.6.0

// problem.mjs
const foo = () => {
  await bar()
}

So "problem.mjs" has an issue, which is that it is using the "await" keyword inside a non "async" function.

If you try to run this file as an entry in node or regular import, a very helpful error is thrown as expected:

// "node --experimental-modules problem.mjs" or "import problem from './problem.mjs'"
file:///Users/ctsuser1/Desktop/projects/problem.mjs:2
  await bar()
  ^^^^^
SyntaxError: Unexpected reserved word
    at translators.set (internal/loader/Translators.js:27:13)
    at <anonymous>

But... if you try to "dynamically" import "problem.mjs", it throws a completely useless error:

SyntaxError: Unexpected reserved word
    at translators.set (internal/loader/Translators.js:27:13)
    at <anonymous>

Is this a bug? How can this be resolved? It's impossible to debug this way. Thanks in advance!

i think once we standardise our use of module errors in ModuleJob we can streamline decorating the error stack but i'll have to look into it more
