===== Infallible
- `join(a, b)` - Join path `a` with path `b`. `join("foo/bar", "baz")` is `foo/bar/baz`.
These functions always succeed.
- `clean(path)` - Simplify `path` by removing extra path separators, intermediate `.` components, and `..` where possible. `clean("foo//bar")` is `foo/bar`, `clean("foo/..")` is `.`, `clean("foo/./bar")` is `foo/bar`.
