There are many examples of how to implement a switch statement:

http://lua-users.org/wiki/SwitchStatement

If a new control structure were to be added to Lua, there are much more 
interesting control structures out there than poor ol' switch.

An example proposal would replace both while-do-end and repeat-until 
with a single construct.  Dahl's loop-while-repeat statement is more 
general than either of the two other loops, and it allows for more 
elegant expression:

loop
  line = io.read()
while line
  io.write(line)
repeat

I'm not seriously proposing this change for Lua, but I've been wanting 
to use this control structure ever since I learned of it and I know of 
no language which implements it.
