This has the benefit of being slow both on CPython and PyPy. Although
using .format() is even slower. :-)

Did you really try it?
PyPy is really fast with str.\_\_mod\_\_, when the format string is a constant.
Yes, it's jitted.

How about the .format() style: Is that jitted as well?
In order to get people to prefer .format over \_\_mod\_\_,
it would be nice if PyPy made this actually \_faster\_ :-)
