Not so fast Mr. Van Rossum!  We need to get the specifications for
these features written first.  Barry should be updating the PEP
guidelines today, and Tim and Thomas have been assigned PEPs on the
two most controversial features.  Yesterday, I proposed we set Aug. 9
as the deadline for completing the specs.

Until we have the specs, I don't think we need to have lots of
long-winded debates about whether the features scare people :-).
