Thank you John and Evan for this clarification.

I just replaced the egg I posted yesterday with a slightly modified
version.  (Without tagging a new version as it did not make it to the
listing anyways so far.)

Now there are tree modules srfi-101-ra, srfi-101-plain and srfi-101.
The first exports the names with the "ra:"-prefix as given by the
origianl implementation, the second exports those names with the prefix
stripped (manually).

The third currently exports nothing.  It has a line commented out, which
would make export those names from the "-plain" module prefixed with a
single "r" as you proposed here:

I just could not compel myself to believe this single letter prefix
being a good idea, once I did the basic testing.

This is exceptionally hard to read and looks like a typo at the first
glance.  Also this single "r" is not exactly a hint - to me at least -
that this is the analogous definition for a similar data type.

That's why I left it out for now.  It's easy enough to do

(import (prefix srfi-101-plain r))

However if there is enough support for this prefix, I'll reconsider the
semicolon in front of the reexport statement in the egg.
