[Numpy-discussion] __array_wrap__

[Neal Becker]

This seems to work now, but I'm wondering if Charles is correct, that 
inheritance isn't such a great idea here.

The advantage of inheritance is I don't have to implement forwarding all the 
functions, a pretty big advantage. (I wonder if there is some way to do some 
of these as a generic 'mixin'?)

I was concerned that using a vectorize function in __array_wrap__ would 
result in a recursive call to __array_wrap__ (and in some earlier version I 
did get infinite recursion).  This version doesn't seem to have a problem, 
although I don't know why.

Any thoughts?  Code attached.
