Can somebody clarify this for me? What's the situation in 5.2 where the
function keyword wouldn't produce a function object?


function foo()

  local function bar()
  end

  print(bar)
end

foo()
foo()


In Lua 5.1, a call to function "foo" will create a new instance of function "bar" each time. Lua 5.2 will create only one instance if "bar" has the same upvalues each time.
