WIth great respect to all those who are gleefully enjoying the direction
this thread is going, a quotation from the Bible [1]:

  Whitespace of whitespaces, saith the Programmer; all is whitespace.

After all, Lua is whitespace-agnostic; you can just pass your chunk
of code to quite a simple reformatter [2].

Style is much more than that.

It deals with questions such as:

- Do you explicitly code 'nil' in situations where it will be supplied
by default?
- Do you write "y=10*x" or "y=10.0*x" when you know that x is
floating-point?
- Do you monkeypatch globals?
- Do you use closures to encapsulate upvalues?

[1] Modern Geek Version.
[2] Any idiot can write one.[3] My first Lua program (part of my LuaTeX
primer) was just such a reformatter.
[3] Not necessarily a good one. My first Lua program can't reformat
itself (failure to take into account the "--[^\n]*\n" comment construction).
