Forgive me for being obtuse, but I can't see anything significantly simpler in this PEP than the standard string interpolation, except for the case where the identifier doesn't need braces:

template("Hello, $name, how are you?") % {name: "Jim"} versus "Hello, %(name)s, how are you?") % {name: "Jim"} Apart from removing the need for the parentheses/braces in this case, all it does is consistently remove the "s", and replace the % with $, and then limiting the interpolated values to strings (or will it automatically use str(x) for any non-string variable x?). Is there any other benefit to this that I'm overlooking?

The elimination of the trailing 's' is definitely a benefit, as is the adoption of $-placeholders, since that tends to be the placeholder introducing character in many other languages. In terms of usability, it's a win.
