> Random would be a subjectless function that generates a 32? bit random number.  The random number generator need not be cryptographically secure. 
> A use case would be for random be to generate a random pattern across some number of file paths to be used with putFile.
> Example - puts files randomly to /my-dirs/dir-1, /my-dirs/dir-2, /my-dirs/dir-3
> /my-dirs/dir-${random():mod(3):plus(1)}/
