Allow class objects in constructors

please add the class name reference by argument, like this example:

class Foo {
  
}

main() {
  myFunction(Foo);
}

myFunction(class) {
  class f = new class(); //class = Foo
}

This seems like a language tour thing.

i'm freaking up to do this function in my game framework:

instance_create(x, y, obj) {
  var inst = new obj();
  inst.x = x;
  inst.y = y;
  return inst;
}

there is a chance to do this in someway ?

i can't do: instance_create(x, y, new obj())
because also I must reference the "class name" in another function

etc... collideMethodWith(class) etc...

Is this a doc request or a language request?

Allowing this sort of thing is very attractive. We have to be sure of the implications, especially for JS compilation. So, yes, we are considering it, but it may be a while.
Changing the bug description to be clearer.

In the meantime, reflection can help (at least on the VM).
