Of course, I've been elsewhere. But Python currently uses `%' for driving
interpolation, and on this topic, I've been with Python, if you wonder :-).

The distinction between %()s and %()r, recently introduced, has been useful.
But with str() and repr(), only one of those is really necessary. But it
gave the impression that Python trend is pushing for % to get stronger.
The proposal of using $ as yet another formatting avenue makes it weaker.

Noise decreases legibility. So, maybe the PEP should not say that ${name}
is to be preferred over $name? Or else, it should explain why.
