Re: [Visualpython-users] Numpy progress

[Bruce S. <Bru...@nc...>]

That's impressive progress, Art. Yes, by all means ruthlessly remove all 
references to the old machinery. Note that the current scheme of using 
either Numeric or numarray is broken. When Jonathan Brandmeyer first 
made it possible for Visual to use either one, I too tested the 
capability by installing only numarray and it worked except for some 
minor problems with slightly changed numeric syntax in some demo 
programs. Then I was surprised to find this capability does not work 
with recent versions, and I didn't try to find out why, because clearly 
no user of Visual noticed nor complained. I don't know how this 
capability got broken.
