Would be nice to have a value range as parameter
and/or a choice between uniform and 'exponential' distribution.

    num::u64::Any,
    strategy::{BoxedStrategy, Strategy},
};

impl<const BITS: usize, const LIMBS: usize> Arbitrary for Uint<BITS, LIMBS> {
    // FEATURE: Would be nice to have a value range as parameter

    type Parameters = ();
    type Strategy = BoxedStrategy<Self>;

    fn arbitrary_with(_: Self::Parameters) -> BoxedStrategy<Self> {
        // OPT: Copy [`UniformArrayStrategy`] to avoid heap allocations
