Transient environment with standard functions

[Matthew Keeter <matt.j.keeter@gmail.com>]

I’m trying to generate a temporary, transient environment that a useful set of functions in it.

The use case is eval’ing a set of small code strings.  Each environment needs to be
independent, so previous eval’s don’t leave anything in the environment.

I can make a dummy environment with (null-environment 5), but it’s missing everything
useful.  Calling (scheme-report-environment 5) gives me a useful environment, but the
environment is shared (so effects from one eval can carry over, which is undesirable).

Any pointers?  (resolve-module) seems like it could be useful, but the #:version argument
doesn’t seem to work.

Thanks,
Matt
