The documentation sais that all types should have the property .stringof, but it doesn't seem to work. Has it been renamed? Or doesn't it exist (anymore)?

In what case does it not work?

Any case. I tried this:

------------------------------------------
module test;

import std.stdio;

struct Foo { }

enum Enum { RED }

typedef int myint;

void main()
{
    writefln((1+2).stringof);       // "1 + 2"
    writefln(Foo.stringof);         // "Foo"
    writefln(test.Foo.stringof);    // "test.Foo"
    writefln(int.stringof);         // "int"
    writefln((int*[5][]).stringof); // "int*[5][]"
    writefln(Enum.RED.stringof);    // "Enum.RED"
    writefln(test.myint.stringof);  // "test.myint"
    writefln((5).stringof);         // "5"
}
------------------------------------------

And got these errors:

------------------------------------------
main.d(13): Error: no property 'stringof' for type 'int'
main.d(14): Error: no property 'stringof' for type 'Foo'
main.d(15): Error: no property 'stringof' for type 'Foo'
main.d(16): Error: no property 'stringof' for type 'int'
main.d(17): Error: no property 'stringof' for type 'int*[5][]'
main.d(18): Error: no property 'stringof' for type 'int'
main.d(19): Error: no property 'stringof' for type 'int'
main.d(20): Error: no property 'stringof' for type 'int'
------------------------------------------

That works just fine here, DMD 1.007

Ah, I have DMD 1.003. Would that make the difference?

Seeing as .stringof was added in DMD 1.005, it might. ;-)

Strange. It wasn't even so long ago that I downloaded the compiler. Has stringof only existed for a month or so?

Yes, it has not been announced as part of the language. Walter said it was because it didn't work correctly. And it really doesn't, at least for enums. For example, this gives int while Test is expected:

enum Test : int
{
	one
}

void main()
{
	pragma (msg, Test.stringof);
}

Well, it's handy nonetheless. I'm using it in some assert(0) error messages.

Thanks for the help, everyone. I'll update the compiler.
