After a second thought: this doesn't have to be special case. The 
obfuscator can build a table putting in there all the string keys and 
all the string values (may be excluding those involved with `require'). 
Then it replaces all those strings with their obfuscated counterparts.

That way:
  d = {	  one = 1, [1] = "one",
	  two = 2, [2] = "two",  }
will become:
  a1 = {  ["a2"] = 1, [1] = "a2",
	  ["a3"] = 2, [2] = "a3",  }
