This is what I did:

-- this code is extracted from test/readonly.lua
local f=function (t,i) error("cannot redefine global variable
`"..i.."'",2) end
local g={}
local G=getglobals()
g["foo"] = 0 -- tu: predefine global "foo", so "function foo() ..." doesn't fail

-- test function
function foo() x = 1 end

foo()  -- no error (tu: actually this *does* cause an error for me)
y = 1  -- error
