Research direction
Start by reviewing the example in BurntSushi/byteorder#68 and the existing unreachable!() lint handling in rust-clippy. Determine how conditional nesting and code purity should be identified. Done means the lint reliably flags unconditional unreachable!() calls while avoiding calls after non-pure code, with coverage for the relevant cases.
