Then either don't import both or use the full import.

auto file = std.stdio.File("filename");

But I wouldn't advise using std.stream for anything unless you have to. As the 
note in its documentation states, it's considered out-of-date and will be 
replaced.

It's missing new. My mistake.

auto buffer = new ubyte[](4);

or as David pointed out, you get just allocate the array in the rawRead call:

auto buf = file.rawRead(new ubyte[](4));
