json.writer: Allow more objects to be keys in >json. Not completely sure about -Infinity being a key when ``jsvar-encode?`` is true. See #1189, this might solve it but we need more stress testing it.
tools.gc-decode: fix for 32-bit.
tools.gc-decode: fix for 64-bit.
tools.gc-decode: fix (again) for 64-bit.
json.writer: Didn't end up using present vocab after all.
tools.test: Print tests homoiconically. There is too much spacing still
but it's better than before imo. See #1221.
parser: Print "Loading" message as a comment for homoiconicity. See #1221.
tools.test: Fix using list.
