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.
