Tests tests tests
- tests for #Copy
- added a “disable” helper to disable specific tests instead of just commenting them out
- “disable” will print out warnings about disabled tests (hopefully with links to corresponding issues)
- cleanup bug repro that has been subsumed into tests

# to test the value of stdout, pass --stdout=string (if not provided, stdout is not verified)
