@codeadict do you consider this mergeable or WIP? (apologies for not being here earlier, was thinking the PR is a draft)

[codeadict]

@ioolkos its not mergeable yet. I have to fix lots of Lua tests still

[ioolkos]

@codeadict ah yes, I missed that, thanks!

@ioolkos , @codeadict: I worked a little bit on this one and "made it work" for Lua. See https://github.com/mths1/vernemq/tree/json_thoas (and then vmq_diversity_json.erl)

• I was not able to get lua working with iolists, so I reverted to binary
• There was a small issue in

json_to_lua(?JSON_EMPTY_OBJECT) ->
?LUA_EMPTY_TABLE;

which was driving me nuts as #{} for whatever reason matches also an non empty maps...
