ASCII Art

[Rapin Patrick <rapin.patrick@...>]

Hi,

I just discovered an interesting Lua syntax feature.
Provided you define that simple function :

  function _() return _ end

The following code actually compiles and executes without error :


  _() ()

You can of course pass dummy arguments to _ function :

  _(___)(_,_)

And since you can omit parentheses on functions calls with table constructors and literal strings:

  _{} "" '' [[  ]]


You should be able to draw beautiful Lua program in ASCII Art.

       _(
      _)()
     {".."}
    (_,{}){}
   '////\\\\'
  {}(){___}[=[

 ::--.--::]=](_)

The main problem being that I have always be very bad for drawing :-(
