I really appreciate comments from those who remember some of the old 

There are indeed some different needs.  Most of this, however, is in the 
ufunc object (how do you do math with the arrays).   And, a lot of this 
has been ameliorated with the new concepts of error modes that numarray 

There is less argumentation over the basic array object as a memory 
structure.   The biggest argument right now is the design of the object: 
i.e.  a mixture of Python and C (numarray) versus a C-only object 

In other words, what I'm saying is that in terms of how the array object 
should be structure, a lot is known.  What is more controversial is 
should the design be built upon Numarray's object structure (a mixture 
of Python and C), or on Numeric's --- all in C
