Though I suggested two options, I prefer the option that adds language
to the report that signals that this is a bad idea, rather than 'load'
taking an optional argument. Imagine at the REPL that I request module A
(via normal use of 'load' or some other implementation specific method).
Module A imports module B, and module B contains the call
(load "foo.scm" (interaction-environment))
Then, B's exports are now available for A, and A's exports are now
available to me. But what about any definitions from "foo.scm"? Are they
now also available to me? If so, it seems messy, because B now has a
signature that includes both its exports and side-effects to the
interaction environment. And that changes A's signature as well.
Thanks,
Jon
