sys = require 'sys'
#oo love:
class MyMath
	square: (x) -> 
		x * x
	cube: (x) -> 
		this.square(x) * x
#functional love:
printSquare = (number_to_process) ->
	"square(#{number_to_process}) = #{myMath.square(number_to_process)}" #<- why does this work? myMath should be out of scope in here!
#let's get something rolling:
myMath = new MyMath
x = 3
#mind the nice string processing:
sys.puts printSquare(x)
sys.puts "cube(#{x}) = #{myMath.cube(x)}"
#what's next - dynamic dispatching ;-)?

OK, dynamic scoping... if I remember that right, there's a global binding for variables in that. Reminds me of Pascal back then, now I understand.

Wonder if that's an aspect that Crockford discusses in "JS: The good Parts" ;-).

Thanks!
