Why is this code returning the wrong type?

[Gary Willoughby]

Hmmm... Following your example i'm still having problems 
compiling this simple snippet:

import std.stdio;

class Example
{
	private FILE _file;

	public this(string file)
	{
		this._file = File(file, "r");
	}
}

Error:

test.d(9): Error: cannot implicitly convert expression ((File 
__ctmp1220 = 0;
  , __ctmp1220).this(file, "r")) of type File to shared(_iobuf)
