in stepper/private/marks.rkt
- in mark-binding-value, add exception handler to catch undefined vars, so
display-mark in break works with recursive fns
in /tests/stepper/automatic-tests.rkt
through-tests.rkt
- add inf list example from icfp paper
in stepper/private/model.rkt
- refactor send-step to use cond instead of unless
- in send-step, when highlight-stack = null and last-rhs != null (and lhs !=
last-rhs), send a step with lhs = last-rhs (previously skipped whenever
highlight-stack = null)
- basic filter example wasnt showing result without this
- in icfp inf list example, this shows some intermediate forcing states
- all other existing tests passed
