Re: Obtain Random.self_init seed

Random.get_state () will return the current state of the random generator.
This is of the abstract type Random.State.t, but it is reasonable to assume
it is marshallable. Calling random-generation function mutates the random
state in place; so if you plan to first generate random numbers and only
later decide whether you want to keep the initial state around, you should
use Random.state.copy to make an independent copy of it that won't be
affected by random-number generation, and save the copy.
