That is, indeed slow, but it's not suprising, the code around
format-json isn't the most performant thing. I plan to improve on that
in the future.

That is - at least to me - good news, because in 3.4, format-json became
a lot smarter. If we managed to keep the same speed, that's not bad!

Nevertheless, this is an issue I'm aware of, and have plans to improve
the situation. I'm not entirely sure I can do that within the scope of
3.4, but there's a possibility I can make improvements even there. We'll
see, as soon as I get there on my TODO list.
