Random value from array? (Also: ™Bells+Whistles)
How do I make an array of values and then choose randomly from that array?
Next I'd like to add weights. In SC that would be Pwrand. Next I'd like to empty out all values before putting all values back in the array and then choosing randomly again. In sc that would be Pshuf. Next I'd like make sure there are no repeats of values ever. Not even when comparing the last value with the first value of a new shuffling. I don't know how to do that in SC.
