Summary

Save this as file test:

#!/usr/bin/env -S uv run --script
# /// script
# dependencies = ["requests"]
# ///

import requests

requests.get("https://google.com")

Then try to run something like ty in its environment:

$ uvx --with-requirements test ty check test
error: Couldn't parse requirement in `test` at position 84
  Caused by: Expected one of `@`, `(`, `<`, `=`, `>`, `~`, `!`, `;`, found `r`
import requests
       ^

If you rename it to test.py it works fine:

$ uvx --with-requirements test.py ty check test.py
Installed 6 packages in 5ms
All checks passed!

Since inline metadata is meant for standalone scripts that usually wouldn't have an extension, it would be really useful if this worked.
