... and some of them have come directly from discussions on
this mailing list in the past couple of years.
As an example, the /SKIP refinement to SORT and SELECT was
proposed and discussed on this list prior to its addition
to REBOL/Core.
Personally speaking, I'm always eager to hear from others on
the list about ideas for ongoing improvement. Whether the
discussion on the list reaches consensus (or not), and whether
RT agrees to immediate implementation (or not), I'm usually
stimulated to think hard about the issues raised and feel that
I benefit from the process!

I proposed this one about a year ago. I'm still of the opinion
that it would help reduce namespace clutter and would simplify
an area of the notation that seems remarkably clumsy compared to
the clean elegance of many other parts of REBOL.

Just for clarification...
Could you explain why you would prefer the above SET expression
to the following?
a/b/c: 1 d/e: 2
