or maybe not... I'm doing
```javascript
  ['LOG_DISABLE', 'LOG_ERROR', 'LOG_WARN', 'LOG_INFO', 'LOG_DEBUG']
      .forEach(function(logLevel) {
        Object.defineProperty(this, logLevel, {get: function() {
          return constant[logLevel];
        }});
      });
```

where ```this``` is probably ```global```....
