// The issue boils down to us needing to seed the Random*Generators
// with different seed each, so that they return different sequences
// of random numbers. We do this by giving them a number from the
// shared RNG instance as their seed.
//
// However, this runs into an issue if the reseeding happens each
// time the test case is entered (as opposed to first time only),
// because multiple generators could get the same seed, e.g. in
// ```cpp
// TEST_CASE() {
// auto i = GENERATE(take(10, random(0, 100));
// SECTION("A") {
// auto j = GENERATE(take(10, random(0, 100));
// }
// SECTION("B") {
// auto k = GENERATE(take(10, random(0, 100));
// }
// }
// ```
// `i` and `j` would properly return values from different sequences,
// but `i` and `k` would return the same sequence, because their seed
// would be the same.
// (The reason their seeds would be the same is that the generator
// for k would be initialized when the test case is entered the second
// time, after the shared RNG instance was reset to the same value
// it had when the generator for i was initialized.)
