No. Some alternatives are:

t = {}
t.foo = function() end
t.bar = some_global_function(t.foo)

or

local function newtab(f)
local t = setmetatable({}, {__index=_G})
setfenv(f, t)()
  return setmetatable(t, nil)
end

t = newtab(function()
  foo = function() end
  bar = some_global_function(foo)
end)
