"--" can not be passed as argument

[rschmidtner]

Why does python script.py f "--" not work?

# script.py
import appeal

app = appeal.Appeal()

@app.command()
def f(a):
    print(f"Received the following parameters:")
    for key, value in locals().items():
        print(f"  name: {key}")
        print(f"    value: {value}")
        print(f"    type: {type(value)}")

if __name__ == "__main__":
    app.main()
