[Numpy-discussion] Using new numeric instances in NumArray and RecArray.

  Hi all!  I am trying to define new numeric types to use them in
  NumArray and RecArray objects.  My intention is to define them as
  equivalent to other types, but also make possible to distinguish them.
  I tried "MyInt32 = IntegralType(4, 'MyType')", which registered OK, is
  equivalent to Int32, but distinguishable from it.  However, I am not
  allowe to create a NumArray based on it: "a = array([1,2], MyInt32)"
  fails with "RuntimeError: _numarray_init: can't get typeno for type".

      Is it possible to integrate new types seamlessly into NumArray and
  RecArray objects?  Is this the right approach, or am I getting that
  wrong?

  Well, thanks a lot for your cooperation.
