/*!
Try out the obfuscation live!

```
cargo rustc --release --example obfuscation -- --emit asm -C "llvm-args=-x86-asm-syntax=intel"
```

Inspect `target/release/examples/obfuscation.s` to see the compiled code.

These examples are #[inline(never)] to aid inspection of the generated code.
In practice the generated code is inlined and mixed with their surrounding code.
