William,
I'm attaching the patch as I just implemented it. This does the
'right thing' for binary extensions:
In [1]: import strop
In [2]: strop??
Type: module
Base Class: <type 'module'>
String Form: <module 'strop' from '/usr/lib/python2.4/lib-dynload/strop.so'>
Namespace: Interactive
File: /usr/lib/python2.4/lib-dynload/strop.so
Docstring [source file open failed]:
Common string manipulations, optimized for speed.
Always use "import string" rather than referencing
this module directly.
Please let me know if it also provides what you need for SAGE, so I
can commit it to IPython's trunk.
Cheers,
f
