Modern C++ Won't Save Us

What's the modern C++ equivalent to C's

    (rand() % (b - a)) + a;

or Python's

    random.randint(a, b)

Easy to use and often good enough.

This is no longer uniform, because it introduces a bias towards small numbers.

Yes, it's less than ideal. But like I said, often good enough. Sometimes you just want a simple way to get something approximately random, the actual distribution might be unimportant.
