It's apparent you have negative pre-conceptions about scipy (even though 
scipy has always just built on top of Numeric so I'm not sure what your 
difficulties have been).  This is unfortunate.  scipy.base is going to 
be a lot more like Numeric than scipy was.  So, I think you can relax.

This is only because the conversion hasn't completely taken place (I'm 
not importing the numeric.py module in __init__ yet because it hasn't 
been adjusted).     Remember ndarray is just a place-holder while 
development happens, so of course quite a few things aren't there yet.  
I've been swamped so far.    from ndarray import * won't even be the 
name to use.   The package won't be called ndarray.   This is all just 
for temporary development purposes.     All of what you belive should 
work will still continue to work.   So, relax.....

Deprecated means new documentation won't teach that approach, that's 
pretty much it.  The approach will still be supported for quite a while 
so people can switch when and if they want.  I don't see "the trouble" 
at all.

Sounds like an exciting move.   Perhaps I can meet you in person if I'm 
in New York or if you are every in Utah.    I sincerely hope you will 
find the new scipy.base to your liking.   I can promise you that your 
concerns are near the top of my list.    It's too bad you can't help us 
get there more quickly.
