Right.  That too.

string.Template is a bit too simplified.  But perhaps it can be adapted.
We still want some way to express %r, %6.2f, etc.    Since string
formatting has been around since Tim was in diapers, we should probably
start by looking at the solutions used by other languages.  With Py3.0,
we have a real opportunity to break-away from doing things the way C
does it.
