As I said, I'm a neophyte.  My "character classes" were based around 
[a-zA-z]  etc.  So you can readily see why the pattern would have 
quickly become unreasonably complex.  I didn't find any definition of 
other character classes (well, not one that meant anything) and given 
the discussion, I think that they wouldn't have worked if I'd gotten to 
the point of testing them.

I was planning on using Chicken to learn scheme, since R7SR is supposed 
to be based more on R5SR than on R6SR, but maybe it's better to learn 
using Racket.  I *trust* the conversion won't be too difficult.  (I *do* 
need to use utf-8 in lots of places, and an incomplete implementation 
while I was learning would be ... unpleasant.  Particularly if the user 
documentation presumed that it *was* complete.)
