Hi Tim,
(Is there a reason why you're using r5rs, out of curiosity?)
Reading docs... ok! Is user-initial-environment a part of r5rs, or an
extension to the standard? I'm looking at:
http://groups.csail.mit.edu/mac/ftpdir/scheme-reports/r5rs-html/r5rs_8.html#SEC65
and I see no occurrence of "user-initial-environment" in the official
R5RS standard.
The following does appear to do something:
###########################################
(display (eval '(+ 1 2) (scheme-report-environment 5)))
###########################################
