Hey,
this sounds in deed like something not easy to do. I can only imagine a dirty
solution where your code just takes a couple of arguments and passing them in.
But if your class has more arguments than you specified, the code will sure not
work.
var obj = new classFn(obj,myArr[0], obj,myArr[1], obj,myArr[2], obj,myArr[3],
obj,myArr[4], obj,myArr[5], obj,myArr[6], obj,myArr[7], obj,myArr[8],
obj,myArr[9]);
This works for 10 arguments which should be more than enough for reasonable
classes. As I said, it is a hack but at least its working for 95% of the
classes.
Best,
Martin
