This ought to prevent stack overflow, but I do not see this actually working: *lua* code crashes with stack overflow when trying to deserialize msgpack from Neovim, Neovim is fine even if nesting level is increased 100x (though test becomes very slow); not sure how recursive function may survive this. So it looks like there are currently only two positive effects: 1. NULL lists are returned as empty (#4596). 2. Functional tests are slightly more fast. Very slightly. Checked for Release build for test/functional/eval tests because benchmarking of debug mode is not very useful.
