this wouldn't work - global in foo is not effecting the execution of
dofile("foo.lua") (except that the variable "dofile" is looked up in foo,
where it isnt found - i guess you didnt mean to do this)

what you want is this: (this already works with lua 4.0)
foo = {}
do
  local t = globals(foo) -- use foo instead of the old globals table. store
old globals table in t
  t.dofile("foo.lua")
  t.globals(t)
end
bar = foo.bar
foo = nil
