Too early, I think. It is Devel software and fails in a lot of my
examples (sometime fails, but often does not give the intended output
which is hard for those who have not tried Trellis to know). Not a
criticism: those of us who used Trellis 1 know how first versions go.

That would be a very small interest (I know it is yours) as for
classification there are almost always better ways.
[Historical note: S-PLUS users lived without all of those for many years,
and the last is only in 2000 and 6.0 I believe. Already R has quite a bit
more than S-PLUS 3.4 of 1996, but also a few gaps relative to that.]

Not really sure what you mean here. R is itself a scripting language,
so in the most common use of `scripting' we have it. Do you mean
the S-PLUS for Windows `script windows'? If so which aspects?
We already have the ability to display code and to submit from it,
which is what was most asked for. (Use Display file from the File menu,
highlight code, use Ctrl-V or the menus.)
