It is impossible to check context in loader's include function

When I use `include: function(path){}` parameter for loader, it is impossible to check context (file which requires this path).
Example: 

``` javascript
    loaders: [
      {
        test: /.svg/,
        include: function(path) {
          //I want to check context here, but it is impossible
          console.log('path', path)
        },
        loader: 'svgo'
      }
   ]
```
