Hello,

I'm fighting with a strange compiler error. This here compiles and runs fine:

---------- main.d -------------

class Foo
{
    static int z = 4;
    static int bar() { return 6; }
    int foobar() { return 7; }
}

int main(string[] argv)
{
    writeln(Foo.z);
    writeln(Foo.bar()); // produces 6
    Foo f;
    writeln(f.bar()); // produces 6;
    writeln(f.foobar());
    return 0;
}

Whereas this does not compile:


---------- main.d -------------

import Foo;

int main(string[] argv)
{
    writeln(Foo.z);	// Error: undefined identifier module Foo.z
    writeln(Foo.bar()); // Error: undefined identifier module Foo.bar
    Foo f;
    writeln(f.bar());
    writeln(f.foobar());
    return 0;
}

---------- Foo.d ----------

class Foo
{
	public static int z = 4;
	public static int bar() { return 6; }
	public int foobar() { return 7; }
}

This is a bit strange for me. Apparently, must be some kind of import problem importing Foo. But I don't see how ...

Thanks for any hints.
Cheers, Oliver

As your class is named the same as your module, writeln(Foo.z) looks for z in module Foo. Foo.Foo.z shoulde give you module.class.instance.
