How do I create a new file using phobos ?

This should be the correct solution to automatically close the file used in 
a BufferedFile stream when leaving the function:

char[][] lines;
...
{
   scope File file = new File("sample.txt", FileMode.Out);
   Stream out = new BufferedFile(file);
   foreach(line; lines) {
      file.writefln(line);
   }
}
