 As a consequence, you have to eleminate sources of `panic!()` one by one, which may be time consuming.
 
 We provide a set of macros `klee_abort`, `klee_assert` and `klee_assert_eq`, that gets fully inlined, allowing KLEE to generate specific tests for each failing assertion. Using these, all errors will be covered by unique test.
