I tried one "file open" example from this site and one from 
another site and neither compiled w/o errors.  I thought perhaps 
I had copied some code that might have been related to a specific 
version of D.  I was just commenting that for people who are 
supplying exmaples/tutorials it would help if they specified more 
clearly what version/genre of D their code sample works with.  I 
have no opinion on the Phobos/Tango or deprecated 
features/version stuff.  I just think it would help the 
acceptance of the language if stuff compiled as listed.

As for the example from this site under std.stdio; it should 
compile.  It's a simple program.  This is the mother site.

A member helped me realize that it needs "import std.stdio;"


// test.d
void main(string args[])
{
     auto f = File("test.txt", "w"); // open for writing
     f.write("Hello");
     if (args.length > 1)
     {
         auto g = f; // now g and f write to the same file
                     // internal reference count is 2
         g.write(", ", args[1]);
         // g exits scope, reference count decreases to 1
     }
     f.writeln("!");
     // f exits scope, reference count falls to zero,
     // underlying FILE* is closed.
}
