Lua seems a very attractive language. What do you use it for? Any  
relation to your Rev work?



I particularly appreciated the following (from <http:// 
en.wikipedia.org/wiki/Lua_programming_language>):


Table as structure

Tables are often used as structures (or objects) by using strings as  
keys. Because such use is very common, Lua features a special syntax  
for accessing such fields.

Example:
point = { x = 10, y = 20 }   -- Create new table
print( point["x"] )            -- Prints 10
print( point.x )             -- Has exactly the same meaning as line  
above


Table as array

By using a numerical key, the table resembles an array data type.

A simple array of the strings:

array = { "a", "b", "c", "d" }   -- Indexes are assigned automatically
print( array[2] )            -- Prints "b"


An array of objects:

  function Point(x,y)         -- "Point" object constructor
    return {x = x, y = y}  -- Creates and returns a new object (table)
  end
  array = { Point(10,20), Point(30,40), Point(50,60) } -- Creates  
array of points
  print( array[2].y )        -- Prints 40
