Thanks Martin. I have updated PEP 3149 with these thoughts, but I'll leave it
up to you to update PEP 384.
I haven't heard a peep since my last RFC on PEP 3149. Guido, would you care
to pronounce on the PEP, or designate someone who can do so (remembering that
Martin is off-line for a while)? If acceptable, I'd like to get this into the
tree before 3.2 alpha 2, currently scheduled for September 5.
