[Python-Dev] Release manager pronouncement needed: PEP 302 Fix

[Phillip J. Eby]

I posted last week about a need-for-speed patch that broke PEP 302 
compliance, and asked if it should be fixed or reverted.  I got exactly one 
response which said "yes, it should be fixed or reverted", which 
unfortunately didn't answer my question as to which one we should do.  :)

If we don't revert it, there are two ways to fix it.  One is to just change 
PEP 302 so that the behavior is unbroken by definition.  :)  The other is 
to actually go ahead and fix it by adding PathImporter and NullImporter 
types to import.c, along with a factory function on sys.path_hooks to 
create them.  (This would've been the PEP-compliant way to implement the 
need-for-speed patch.)

So, "fix" by documentation, fix by fixing, or fix by reverting?  Which 
should it be?
