Re: reference to a local function

It's not an upvalue, it's a regular local value, so you'd need to use
`debug.getlocal` instead (iterate over values and find the one with
the name you are looking for). Something like this should work:

i = 1
while true do
  local name, value = debug.getlocal(1, i)
  if not name then break end
  print(name, value)
  i = i + 1
end
