Closure compiler issues with object
===

I am trying to compile my Js code in [google closure compiler][1] and I am getting error on this code

      var settings = {
                     providers: ['A', 'B', 'C'],
                     interface: 'basic16',
                     apikey: 'XXXXX-XXXXX-XXXXX-XXXXXXXXXX'
                     }


Errors are

    JSC_PARSE_ERROR: Parse error. invalid property id at line 3 character 10
    interface: 'basic16',
              ^
    JSC_PARSE_ERROR: Parse error. syntax error at line 3 character 11
    interface: 'basic16',
               ^
    JSC_PARSE_ERROR: Parse error. syntax error at line 4 character 8
    apikey: 'XXXXX-XXXXX-XXXXX-XXXXXXXXXX'
            ^

But this code works perfect for me in any browser (chrome, firefox, opera, safari, IE7,8,9)
