very interesting.
Finally is our functions,at least one, for/bc compatible with R6RS? i can
not exactly figure it exactly, i see at leats identifier-syntax not in the
library index:
http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-21.html#node_index_start
one day i will have to read the Dybvig article to understand all
that.Perhaps in a near future. ;-)
