Ah.  So "program" means "top-level program" in the R6RS sense.
I'm not sure I like that.

Yes to the first, no to the second, because the REPL session
may use names bound in the REPL but not imported into the
top-level environment.  This is precisely why I don't want
the top-level environment to be different from the REPL.
If you want a clean environment, write a module.
