Not yet, maybe later. Where's my Rebol/C/C++ sizeof when I need it? :-)

Yes. I've noticed their influence in the new core, random on series! is a
nice addition along with the added /skip refinements. I'd still like the
ability to 'shuffle a series, just like we can 'sort a series. I've also got
a few more things I'd like to stuff in there as well.

Here's one:

>>  ChangeRule: func [Search [string!] Replacement [string!]] [
[      reduce [
[           to set-word! 'Start Search to set-word! 'Stop
[           to paren! reduce [
[                'change/part 'Start Replacement 'Stop
[                ]
[           (length? Replacement) - (length? Search)
[           'skip
[           ]
[      ]
>> s: "&" parse s ChangeRule "&" "&amp;"
== true
>> s
== "&amp;"

I've just got to expand it cover a block of search and replacements.

Here's a better shuffle than my earlier one:
Shuffle: function [
    {Shuffles a series, basically undoes 'sort.}
    [catch]
    Series [series!]
    ][
    Pool Index S
    ][
    throw-on-error [
        Pool: copy S: Series
        forall S [
            Index: random length? Pool
            insert/only remove S pick Pool Index
            remove at Pool Index    ; Don't repeat anything.
            ]
        Series
        ]
    ]

I've also got to change my Enhancements and Patches system to cover the
different core and view versions.
