That's what I was trying to achieve. The only gripe I sometimes
have with '%(ident)s' is that users forget the 's' behind 
'%(ident)'; I'd be ok with dropping 2. and only adding 3.

Whatever you do, just please don't mix the old and new 

   'Joe has $ %(a)5.2f in his pocket.' % locals()

is perfectly valid now and should continue to be valid.
