[lua] Incorrect arguments for object containing function

[NeeEoo]

outputs

1, null
2, null

class Test {
	public var func:(Dynamic, Dynamic) -> Void;

	public function new(obj:Dynamic) {
		this.func = obj.test;
	}
	
	public function call(k:Dynamic, v:Dynamic) {
	     func(k, v);
	}
}

class Main {
	public static function main() {
		var a = new Test({
			test: function(k:Dynamic, v:Dynamic) {
				trace(k, v);
			}
		});
		a.func("a", 1);
		a.call("b", 2);
	}
}

meanwhile this works

class Main {
	public static function main() {
		var a = {
			test: function(k:Dynamic, v:Dynamic) {
				trace(k, v);
			}
		};

		a.test("a", 1);
	}
}

so somewhere between it going into a class breaks it

I believe this is due to it generating the function as

function(self, k, v)

generated code for first example:

Test.new = function(obj) 
  local self = _hx_new(Test.prototype)
  Test.super(self,obj)
  return self
end
Test.super = function(self,obj) 
  self.func = obj.test;
end
Test.__name__ = true
Test.prototype = _hx_e();
Test.prototype.func= nil;
Test.prototype.call = function(self,k,v) 
  self.func(k, v);
end

Test.prototype.__class__ =  Test

Main.new = {}
Main.__name__ = true
Main.main = function() 
  local a = Test.new(_hx_o({__fields__={test=true},test=function(self,k,v) 
    __haxe_Log.trace(k, _hx_o({__fields__={fileName=true,lineNumber=true,className=true,methodName=true,customParams=true},fileName="src/Main.hx",lineNumber=25,className="Main",methodName="main",customParams=_hx_tab_array({[0]=v}, 1)}));
  end}));
  a.func("a", 1);
  a:call("b", 2);
end

meanwhile second

Main.new = {}
Main.__name__ = true
Main.main = function() 
  (function(k,v) 
    __haxe_Log.trace(k, _hx_o({__fields__={fileName=true,lineNumber=true,className=true,methodName=true,customParams=true},fileName="src/Main.hx",lineNumber=25,className="Main",methodName="main",customParams=_hx_tab_array({[0]=v}, 1)}));
  end)("a", 1);
end
