If we really want to push for the new api, I think it's fair to change those two lines by simply from numpy import oldnumeric so that scipy also exposes oldnumeric, and let all deprecated names be hidden there. I just tried this change: Index: init.py =================================================================== --- init.py (revision 2012) +++ init.py (working copy) @@ -29,9 +29,8 @@ # Import numpy symbols to scipy name space import numpy.oldnumeric as num -from numpy.oldnumeric import * -del lib -del linalg +from numpy import oldnumeric + all_ += num._all doc += """ Contents and scipy's test suite still passes (modulo the testcobyla thingie Nils is currently fixing, which is not related to this). Should I apply this patch, so we push the cleaned-up API even a bit harder?

Yes please. I think all the modules that still use the oldnumeric names actually import numpy.oldnumeric themselves.
