If you're trying to maintain backwards compatibility with existing syntax, you can't use %ident strings.

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 semantics...

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

is perfectly valid now and should continue to be valid.
