it is probably off topic. I recently got PIL2
Page 139 has pseudo-code for lua require, which avoid infinite loops
mod.lua: print(package.loaded.mod); require "mod"
Based on PIL2, required "mod" should print true, and stop
On lua 5.2.4 and 5.3.4, above code print bunch of nil, then crash.
Does PIL3 and PIL4 changed the require implentation ?
Read Lua 5.3 reference manual, but found nothing.
