Well, for one thing you won't have to write your code all over again when 
std.stream is deprecated, which will happen soon.  std.stdio.File is 
really what you should use for file I/O in new code.

That said, there's a chance it does exactly what you want.  You don't 
have to open a file on construction, there's an open() function which 
opens a file and assigns it to the File handle.  Nor do you have to worry 
about closing the file in the destructor, as it is automatically closed 
the moment the last reference to it goes out of scope.

Here are a few examples of how to use it:

  File file;    // File's a struct, so no need to use 'new'

  // Read a text file line by line
  file.open("foo.txt");
  foreach (line; file.byLine())  writeln(line);

  // Read a binary file in 4MB chunks
  file.open("foo.dat");
  foreach (ubyte[] chunk; file.byChunk(4*1024))
      doStuffWith(chunk);

  // Read up to 100 ints from a file
  file.open("myInts");
  auto buffer = new int[100];
  auto data = file.rawRead(buffer);
