The example used to result in nothing but "declaration uses 'sorry'" (and using the downstream
|
|
"unreachable tactic" linter, the `simp` would be flagged) as `simp` among other elaborators
|

accidentally swallowed the interrupt exception.

Trailing whitespace should not invalidate the module header. Note that in case of a regression, this
|
|
test case will currently deadlock. In any case, it should not succeed as interactive tests
|
|
communicate with one worker process only.
