I'm collecting practical use cases for random.seed() functions. Here's an example of what I'm talking about, in pseudocode:

random.seed(12345);
random() // 0.221038...
random() // 0.858932...

// Switch seeds, get different results
random.seed(6789);
random() // 0.633732...
random() // 0.939101...

// Use original seed, get original results
random.seed(12345);
random() // 0.221038...
random() // 0.858932...

Please comment below with use cases for this function. I've started off with my own use case.

This can be very useful for unit/integration tests of systems that use pseudorandom functions. For example, if I'm building a combat system in a game, I'd like to make sure that the dice roll the same way every time I run tests against the combat system. This way I can verify the expected outcome of combat every time.

For "skill gaming" applications where money is involved, U.S. legislation requires that tournaments provide the same pseudorandom seeds to every participant in the tournament. For example, if we're competing to see who does the best in a solitaire card game, we need to make sure the shuffle comes out the same every time for every player.
