Related to that, this could be a good extension to also add in 5.2.
Such a patch was made in [2] and also suggested in [3] along with
workarounds (e.g. a pure Lua implementation of the bytecode editing).
This limitation currently complicates luac.lua [4], even more-so when
running it under interpreters other than lua 5.1. (Personally, I
don't usually see much harm in debuginfo though.)
