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)?

Thanks,

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.

I think that it would be good if the docs could mention with which 
compiler version a feature was added.

Not for .stringof it doesn't :)

By the way, it would be nice if .stringof for an enum member would 
return the actual enum stringized. Will this be possible?

And it's not very practical to read the doc and searching the changelog 
to see where that particular feature where added.

Note that Kevin Bealer has made two versions of a template for 
'reflective enums'.

I don't find the result totally satisfying as you loose the type safety 
in current version, but it's a good start.
