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)))
