You think it's reasonable to have a function called arc4random, even though we know arc4 is insecure and creates biased (i.e. not pseudorandom) output, yet as we know that arc4random really is not "random numbers based on (a)rc4", because internally it's using something secure? So you'd have to actually know that this function named after an insecure stream cipher is a secure way to get random numbers?
