Environments

[Sjoerd van Leent Privé]

Hi Everyone,

What I like to do is to let the user give a "driver" library and pass that "driver" library around which implements a certain procedure. Using the eval procedure together with a small instruction and a ad-hoc generated environment would let the software be pretty free of things flying around with ill side-effects. Anyone an idea how I could do this in a portable way?

I have been trying to do this using the construct (environment, import-spec), however, this doesn't appear to include the default things which the "guile" library provides (such as quote, unquote, quasiquote and the likes). When using the (scheme-report-enviroment 5), it appears not to be possible to pass along additional import-spec elements.

I know it is possible to pass "guile" along, however, this is not very elegant in portability.

Also, I would like the environment to be destroyed afterwards (as I don't want the environment to leak unwanted side-effects).

Anyone an idea about how to do this?

Thanks in advance,
Sjoerd
