Why is it that if I have a module that I am using to import other 
modules, it never works?

foo.d -----------------------
module foo;
int myfoo = 1;

bar.d -----------------------
module bar;
int mybar = 2;

everything.d ----------------
module everything;
public
{
	import foo;
	import bar;
}

test.d ----------------------
import everything;
import std.stdio;
import std.string;
int main(char[][] args)
{
	writefln(format(myfoo, mybar));
	return 0;
}

-----------------------------

In my mind, this should output "12"...

Instead I get

test.d(6): identifier 'myfoo' is not defined
test.d(6): identifier 'mybar' is not defined

can someone tell my the trick to this? I hate having to update the 
imports of all the files all the time, so i want to centralize it...

And how do you use / what do you use

package
{
  ...
}

for? The documentation on modules and packages seemed a little vague.

What if i don't want to write all that? How to do import something into 
the public level? Isn't that what the public keyword is all about? I 
thought using "everything.foo.myfoo", or actually "foo.myfoo" (i believe 
is the actual way to do that) was only to make clear which one to use in 
the case of a name conflict...

Any ideas?

That's new to me. Where's that?

It worked fine for me. Are you sure the posted code errors for you?
