FWI I changed the printing of datum labels (i.e. #N=DATUM)
to start at 0 rather than 1. The former seems more common
among Scheme implementations, and matches the example in R7RS.
BTW the write procedure now prints datum labels if a cycle
is detected, but not for other shared structure. Use write-shared
for the latter, or write-simple to save time and space by
avoiding cycle detection. This matches the R7RS specification.
