I might do that.  But, its not the R level since those features already
I¹m just mimicking them at the C++ level.  The R transcript was a proof of
concept to make sure this was actually doable.

Well, it might be relevant to other functions, but as you have guessed it
mainly an issue with RNGs.

Well, like I said, someone else did ask me why it was missing.  And
others have wondered as well.  Anyways, it is trivial to fix as I¹ve shown.
I¹m wondering if these can be generated via the pre-processor since they
rather simple.  If I make any progress, maybe it would be worth a Gallery
