It's really not possible to call functions in modules like in any 
other languages? :S

---------------------------------------------------------------
import std.file;
import std.path;
import std.stdio;

//const ROOT_DIR = dirName(thisExePath());
int someInt = 0;
string someString = "sfgsdgdf";
writeln("one");

void main(){

}
