| This is unsafe and dangerous. The returned pointer is only valid for the lifetime | ||
| of the current environment. Using it after the environment exits, or from native | ||
| code that assumes a different thread or lifetime, can crash the process or | ||
| corrupt memory. |

Heh, I love this comment. "Here you go! Have fun cutting yourself!" 😆
Is there someway we could make this safer by returning an opaque value that becomes invalid when the environment exits or if it is used from the wrong thread?

Lol. Thanks!
Unfortunately not. In FFI I'm avoiding abstractions to eventually get to a real value. The pointer is a raw memory address, with all its danger, a-la C style :)
