```

## Command Line Options

| Option | Description |
|--------|-------------|
| `-e 'code'` | Execute code (modern features always on) |
| `-c` | Check syntax only |
| `-w` | Enable warnings |
| `-v` | Show version |

## Notes

- Modern features (`say`, `state`, `//`, signatures) are always enabled — no `use feature` needed
- XS modules are not supported; native Rust reimplementations are provided for common modules
- `-I` is not supported; use `PERL5LIB` environment variable to add include paths
