You should remove the 'const' here, but otherwise the assignment is

Wouldn't that affect `arg`? Or is `arg` created before any argument
processing takes place?
'arg' is created before any processing, because it is available to
that processing:
-- t2.lua
print(#arg)
$ LUA_INIT='@t2.lua' lua -l t2 t2.lua b c
--> 2
--> 2
--> 2
-- Roberto
Does this mean the result of -l could be tweaked by a LUA_INIT script?
Wait, this behaviour should be tweaked...
What if `lua` loaded everything into `arg` as it appears, then started
up LUA_INIT, then started processing `arg` and moving the elements
around, so e.g. your command would print:
--> 5
--> 3
--> 2
Then LUA_INIT would be able to process -l, thus doing what dirk wants.
