And when issue of usability doesn't even get considered until a few

the results can't be be reproduced ...?
I'm inclined to add both an option (to specify a seed, replacing the
environment variable) and a flag (to seed from the system clock or
whatever), and having the PRNG generate a fatal error if neither of
those are used.
That way, neither of the likely problems can arise by oversight.
I guess there is a lot to say for both approaches, which is why I
think the suggestion of Markus is a very good one! +1 from me<br>
