Hi all,

Array has a nice feature where it can take an object and return an  
array containing the object (or if the object is an Array returns the  
object unchanged. So Array(1) is [1] but Array([1,2,3]) returns  
[1,2,3]. I’d like to define a similar type of method for my own class  
but have no idea how to define it. Is there a special function I must  
define or is this an Array only specialty?

Whoops! Never mind just realised Array() isn’t a class it’s a method on  
Kernel.
