INTERACTIVE-EVAL is a wrapper of EVAL used in implementing the REPL. It
does two things: (1) sets *, **, etc., and (2) is a last-chance catcher
of exceptions.

Clearly you don't want the overhead of (1) in EVAL.

And I don't think you want EVAL to be a last-chance catcher of
exceptions, since you do want (EVAL '(+ 'FOO)) to signal an

Maybe Interpreter.run() should be the last-chance catcher.
