It depends on what are the applications of such an array.

For arrays that dimensions ought to be truely undefined you
can implement your own array class.

On the other hand, have you looked at the resize method
of a Numeric array:

>>> from Numeric import *
>>> a=array([])
>>> a.shape
(0,)
>>> a.resize((4,))
>>> a.shape
(4,)
>>> a.resize((2,))
>>> a.shape
(2,)

Note that you cannot use `a` slices before calling
the resize method.
