iport std.mmfile;

struct Database
{
     this(string filename)
     {
         this.filename = filename;
         file = new MmFile(filename, MmFile.Mode.read, 0, null);
     }

     ~this()
     {
         if (file)
         {
             destroy(file);
             GC.free(&file);
         }
     }
}

//somewhere in code:
{
     Database db = Database("somefile");
     ....
     //here at the end of scope I want to be sure that file map is 
closed.
