There is a thorough Lua coding convention from the LuaRocks project
https://github.com/luarocks/lua-style-guide This style guide is very picky about code readability.
I was expecting to find precedence-related recommendations there,
but I've found nothing.
Is the problem really not that much?
Should I just memorize the Lua precedence rules and stop whining about "operator precedence hell"? :-)
