Of course it does. RR and its cousins have a different paradigm for
variables, which is part of the reason why BA referred to them as
"containers" in the original HC, which is appropriate on so many
levels. It's also why I decided to start the Tao of RunRev project.
I'll probably make an announcement on this and ask for posts shortly.
Oh hell, I'll just start a new thread and do it now.

I tend to disagree. This is similar to the argument that
traditionalists in more conventional 3GL and 4GL's make for typing all
variables, even if the compiler will do it for you. I couldn't
disagree more. If you embrace the Tao then this is unnecessary.
Remember, this is a different paradigm.
On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
and did a little diving.
And God said, "This is good."
