This is a novelty and I think this is how some angry people think all LLM assisted programming works. The snippet asks the LLM to implement the function at runtime and run the code w/no human in the loop.
No one is promoting doing this
```python
from manifest import ai
@AI
def is_optimistic(text: str) -> bool:
""" Determines if the text is optimistic"""
assert is_optimistic("This is amazing!")
```
