Are you saying that the bindings established by the rest of the
program are not seen by eval ? If so, are you aware of the following
construct (taken from
http://community.schemewiki.org/?scheme-faq-misc#sicp) ?

((eval `(begin (define ,name #f)
                (lambda (val) (set! ,name val)))
        (interaction-environment))
  value)

Piping the needed values through lambda as in the above will let you
control which definitions can be used, and might be enough for what
you are trying to achieve.

Correct. This means that a new interaction environment will be
generated each time eval is called.

Hope this helps,
