You're right, I've forgot to include noop function in tests list. Here
are the updated timings:

$ time lua estrbench.lua empty_upvalue 1000000000
      142.28 real       133.89 user         0.90 sys
$ time lua estrbench.lua nonempty_upvalue 1000000000
      174.01 real       163.54 user         1.18 sys

These should be similar, since both involve an upvalue load and a compare of the same type of object.

local nonempty_upvalue = function()
  local a = "nonempty"
  return a == nonempty_string

Was the script doing a table lookup for "nonempty_string"?
