Oh wow, today I learned about env -S - when I saw the shebang line in the article, I immediately thought "that doesn't work on Linux, shebang lines can only pass a single argument". Basically, running foo.py starting with

    #!/usr/bin/env -S uv run --script

causes the OS run really run env with only two arguments, namely the shebang line as one argument and the script's filename as the second argument, i.e.:

    /usr/bin/env '-S uv run --script' foo.py

However, the -S flag of env causes env to split everything back into separate arguments! Very cool, very useful.
