mea culpa! It's true that this is not as flexible as a built-in solution.
Using the debug library could tell you exactly the current name of the
script, so that
if debug.getinfo(1,'S').short_src == 'mod.lua' then
---
end
should work - (actually tested it this time ;))
That's rather verbose, but could be wrapped up as a requireable module
if require 'this_mod' 'mod.lua' then
end
where this_mod.lua returns a suitable function.
Since it _can_ be done with Lua, and a robust solution can be made
into a module, such a feature is unlikely to ever get baked into the
language. Lua provides mechanism, not policy...
