I think the below example clarifies everything.

entry.d
=======

module project.entry;

import std.stdio;
import project.other;

void bark(){
	writeln("Woof");
}

void main(){
	project.other.callbark();	
}




other.d
=======

module project.other;

import project.entry;

void callbark(){
	project.entry.bark();
}
