**Unreleased**

62/76 GNU find features supported.

- Rework optimization levels
  - `-O1`
    - Simple boolean simplification
  - `-O2`
    - Purity-based optimizations, allowing side-effect-free tests like `-name` or `-type` to be moved or removed
  - `-O3` (**default**):
    - Re-order tests to reduce the expected cost (TODO)
  - `-O4`
    - Aggressive optimizations that may have surprising effects on warning/error messages and runtime, but should not otherwise affect the results
  - `-Ofast`:
    - Always the highest level, currently the same as `-O4`
- Color files with multiple hard links correctly
- Treat `-`, `)`, and `,` as paths when required to by POSIX
  - `)` and `,` are only supported before the expression begins
- Implement `-D opt`
- Implement `-D rates`
- Implement `-fprint`
- Implement `-fprint0`
- Implement BSD's `-f`
