 This means you can explore various different possible choices by passing different *seeds* for Miri to use for its pseudo-random number generator.
 The following little shell snippet will run Miri with many different seeds, which is great to be able to locally reproduce a failure that you saw on CI, but that you are having trouble reproducing:
