[Chicken-users] making environments

[Michele Simionato]

Hi Felix,

I have some issue with environments. I would like to generate
a custom environments which is equal to the current 
environment (interaction-environment) plus a set of
custom defined bindings. I don't want to pollute the 
(interaction-environment) with those new bindings, so 
I thought: "I will copy the interaction-environment and 
extend it with the new bindings".
However I get the following:

#;> (require-extension environments)
#;> (define my-env (make-environment))
#;> (environment-copy (interaction-environment) my-env)
Error: can not copy interaction environment

So, how do I go? It would be enough for me to start
from a r5rs-like environment. The problem is that
make-environments returns a completely empty environment
which is not what I want (I want to evaluate Scheme
code in this environment).

TIA,
