One of the authors of the code and a senior member of the mailing list
pointed to the standard definition to be used when discussing
derivatives of Lua software. I have pointed to where the discussion
veered into what I consider the mistake of redefining terms for the
sake of redefining terms. If you and Etine consider *that* a mistake,
it is your right (duty?) on the mailing list to state your opinion.
Mine opinion still stands. :)
