Currently, indexed properties are correctly copied
onto the sandbox by CopyProperties().
This will break when CopyProperties() is removed
after adjusting NamedPropertyHandlerConfiguration
config() to use property callbacks from the new
V8 API. To fix it, we will set a config for indexed
properties.

This test is a preparation step for the patch
that removes CopyProperties().

Perhaps we could just use a multi-line template string here instead?

Not sure I understand. @mscdex, could you be a little more specific, please? :)

Instead of +-ing several strings, we can use one multi-line string by using backticks.

 const code = `Object.defineProperty(this, 99, {  
      value: 20,  
      enumerable: true  
 });`; 

It's less characters total and you can copy and paste such strings into the REPL without removing all the ' + ' in between.

Thanks @fhinkel. The code is revised now.

const vm = require('vm');

The indentation looks off on lines 8 and 9. Other than that, LGTM.
