Because nobody has mentioned this yet: I know, that rails defines a 
method with that name in Array, but I think it is a bad idea. It breaks 
existing and future code, that expects Array#rand to be Kernel#rand and 
have the same signature and semantics of it, while being in context of  
an Array instance. It makes it much more difficult to get any random 
number out of ruby in this context, even if you are aware of Array#rand.
