I don't need them.  I was just curious.

I updated a script I had to try to exercise all possible
number, character, identifier and string branches in a R6RS parser.
I used it to examine the parsing differences between Guile-1.8.x,
Guile-1.9.x, and MzScheme, which was rather amusing.  The exact,
complex number is partially implemented by MzScheme.

Thanks,
