Hey!
MIT/GNU Scheme provides a very nice user interface for this:
1 ]=> foo
;Unbound variable: foo
;To continue, call RESTART with an option number:
; (RESTART 3) => Specify a value to use instead of foo.
; (RESTART 2) => Define foo to a given value.
; (RESTART 1) => Return to read-eval-print level 1.
2 error> (restart 1)
;Abort!
1 ]=> (+ 2 "foo")
;The object "foo", passed as the second argument to integer-add, is not the correct type.
;To continue, call RESTART with an option number:
; (RESTART 2) => Specify an argument to use in its place.
; (RESTART 1) => Return to read-eval-print level 1.
2 error> (restart 2)
New argument: 3
;Value: 5
