And of course, how can you help but try it for real when it's only 3 lines
in a nice self contained @key and only needs one variable even though I
wasn't going to?

Yes it works. Although I see that I forgot to seed rand, so it will probably
always generate the same list of "random" passwords.
so stick a x = rand("-1") somewhere like @once or @entsel or @menu and that
will take care of that.
