Haxe global (like) functions and variables via import

Global.hx

package;

class Global
{
  public static function parseInt(s:String):Int { return Std.parseInt(s); }
  public static function int(f:Float):Int { return Std.int(f); }
  public static function is(v:Dynamic, t:Dynamic):Bool { return Std.is(v, t); }
  public static function typeof(o:Dynamic):Type.ValueType { return Type.typeof(o); }

  public static var DEBUG_LEVEL:Int = 3;
}

Main.hx

package;

// In Haxe you can't (easily?) define a global function or variable, but you can
// import static functions and vars so your syntax looks like using globals.

// e.g.
// all static members of Global are now in scope, both functions and vars
import Global.*;

class Main
{
  public static function main()
  {
    trace("parseInt: " + parseInt("51"));
    trace("5 is int? " + is(5, Int));
    trace("int(Math.PI) = " + int(Math.PI) );
    trace(typeof([]));
    trace("DEBUG_LEVEL > 2 ? " + (DEBUG_LEVEL>2));
  }
}

can you general js code in haxe without use Global.parseInt ?only function parseInt(value:string)?
