Adding jvr and people interested in import machinery, per Misc/maintainers.rst

Michael, can you refresh your patch against the py3k branch? Please also generate a unified diff from the top level of the source distribution, as detailed in http://www.python.org/dev/patches/ The feature seems useful to me and the patch is straightforward. Tests and doc updates are needed; do you want to add them?

Mark, I think that feature requests are never closed just because they’re old; they have to be rejected, implemented or obsoleted. (Thank you for all your triage work.)
