ES6 Parsing seems to be Broken with 2.2.1

[sbrandtb]

When using version 2.2.1, parsing ES6 files seem to be broken:

Error parsing factories/<some-file>.js at line 44 column 61, where the file contains ::this.unserializeEvent);

When downgrading to 2.2.0, this does not happen.

Ok, after looking into the commits, I admit that it's just the warning that's missing. Still, can someone explain why it's not parsing?

Maybe this commit has something to do with it...

@rubenv could you take a look?

In my case it's broken because of imports. By default espree engine for parsing use script option. When your project uses modules it has to be set to module.

syntax = espree.parse(src, {
  attachComment: true,
  loc: true,
  ecmaVersion: 6,
  sourceType: 'module',
  ecmaFeatures: {
    jsx: true,
    experimentalObjectRestSpread: true,
    globalReturn: true
  }
}); 

I'm not sure tho if it should be changed globally or passed thru configuration options.
