Would the generated values fill the whole int range, i.e. 64 bit on modern
systems?
And would it make sense to add max and min for the generated values like we
have with random_int()?
Because mapping arbitrary int values to a specific range is error-prone: Just
using modulo leads to bias in the resulting values.
