Should say "random sampling from an array"

[bootchk]

First, thanks, I enjoyed reading the code and the humor here.

I think the code is a good tutorial in random sampling from an array. I needed the one line of code that gets a random index on the parent. (It also seems a good tutorial how to define methods on a new type.)

Is it really "random based" or should you say "every based" or "not based" or "always shuffled?" A strange beast indeed.
