Just while we're on the topic of random numbers . . .

How many of us here have written quick sample code and had to
copy-paste the code for setting up the random number generator?

I think C++ should have something like the following:

    std::array< uintptr_t , 666u > var;
   __rand >> var;

    std::vector< uintptr_t > var;
    var.resize( 666u );
   __rand >> var;


'__rand' would be an object of a type that has 'operator>>' defined to
populate any kind of object with random bytes. Maybe something like:
