Hi Marijn,
This just reflects that "guile -c" doesn't preload the (ice-9 r5rs)
module (and the same is true of "guile -s"), whereas the guile REPL
does.
Is this a practical problem for you? It can be worked around by
something like this:
address@hidden:~$ guile -c "(begin (use-modules (ice-9 r5rs)) (write
(scheme-report-environment 5)) (newline))"
#<interface (ice-9 r5rs) b7c71e40>
Regards,
Neil
