How to use the keyword 'Object' ?

All,
my goal is to build a function type - or a method - which accepts any type structure, like for example:

type base
function create(t:type)
local test:t = new t
return test
end type

The above code does not compile: seems that 'Type' can't be defined as parameter.

So I tryed with 'Object':

type base
function create(t:Object)
local test:t = new t
end type

But no luck.

The goal here, is to make something like:

type base
function create(o:whatever)
local test:o = new o
end function
end type

type A extends base
end type

type B extends base
end type

.
.
base.create(A)
base.create(B)

Am I missing something obvious here ?

So far, the way to make what I mean, seems to be this:
type base

function create(o:base)
.
.
end function

type A extends base
end type

type B extends base
end type

.
.
base.create(New A)
base.create(New B)

This works, but I wanted to create the base class in such a manner that I can make that 'New A' or 'New B' in the function body - that is, inside the base type function, instead of in the function call.

In other terms, the base type should be able to create a new type instance, without to know which type is passed to it.

I hope I explained the question; another example could be the Object implementation in VB.NET:

function set_text(control as Object)
control.text = "hello"
end function

you can then call the above function with any 'object' - all of them should have, of course, a property called 'text' in order to work.

In the following example, the function is called with two different object types, a label and a textbox:

dim lab as new label
dim tex as new textbox
set_text(lab)
set_text(tex)

Thanks in advance,

you can't do it this way

You can not use objects to create new objects, new is meant for Typenames like base. there is no "new like object" command
