There will be both. :-)

Off the top of my head I'm not sure whether the interval will be [0.0, 1.0], [0.0, 1.0) or whether it might be possible to make it work with arbitrary boundaries. If I recall right, most uniform01 implementations are [0.0, 1.0) ... ?

It's the best chance to improve naming, so do not throw it away for nothing:

If you want you can keep a deprecated randomShuffle alias name for some time in std.random2.

Yes, in that case, I'd be happy to make the change (and maintain the old names via aliases). Thanks for pointing me to the bug report; I'd forgotten that this was an open issue :-)

We will probably have the nice Andrei's allocators in Phobos, but not in a short time. So I suggest to not rely on them for std.random2.

No, I don't intend to rely on them arriving soon. But while of course a random3 is always possible too, I'd rather not be faced with the situation of needing breaking changes to handle support for alternative allocation strategies. So if necessary, I'd rather maintain std.random2 outside of Phobos for a while and get things right when it finally lands, than push it in too early and need to make breaking changes.
