Comment (by mpickering):

 `-ddump-json` is a bit different to the other `-ddump` flags as the goal
 is to dump all the output (including the output of other -ddump flags) as
 machine readable JSON.

 The output of using `:set -ddump-json` looks more like I would have
 expected but I hadn't really considered the interaction with ghci.

 How do you think `-ddump-json` should work with the normal `ghc`
 executable?
