Just to be clear -- the above is the current numarray v1.0 behavior
(at least on my machine).  Numeric compatibility would additonally
require that

import numarray
a = numarray.arange(10)
theTypeCode=repr(a.type())
b = numarray.array(a, theTypeCode, copy=0)
print a is b
b = numarray.array(a, copy=1)
print a is b

produce

True
False

While currently it produces

--->

False
False

Having said this, I can work around this difference -- so either
a note in the documentation or just removing the copy flag from 
numarray.array would also be ok.
