Isn't there a simple 'includefile' method out there that, ala #include, just inserts the relevent text? It strikes me that this would do exactly what Thomas is looking for, without requiring poisoning of his global tables.

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 = {}
  local t = globals(foo) -- use foo instead of the old globals table. store
old globals table in t
bar =
foo = nil
