Subject: Creating a varargin-like object

I use the Debian package octive2.1 version 1:2.1.72-10.

Here is an octave interactive session:

octave:1> c = cell(2)
c =

{
   [1,1] = [](0x0)
   [2,1] = [](0x0)
   [1,2] = [](0x0)
   [2,2] = [](0x0)
}

octave:2> c{:}
ans =

(,
   [1] = [](0x0)
   [2] = [](0x0)
   [3] = [](0x0)
   [4] = [](0x0)
,)

What kind of an object is c{:}? Note the curly brackets.

The octave source code is full of stuff like:

function plot (varargin)
   __plt__ ("plot", varargin{:});

Why are the curly brackets used?

Suppose I have a collection of strings 'A', 'B', ... What should XXX be in
the following:
     XXX = ?????
     menu('sometext', XXX)
so that the choices in the menu are 'A', 'B', etc. In other words, how do I
create a varargin-like object from scratch?
