Thank you for the explanation.

I think set0 is very good name. The name tell its function well.
So I'll push set0 to the bash maintainer.

However, I think extending the original `set' command to handle $0 is
not so bad. So I'll propose both the name set0 and extending set to
the maintainer, and I'll get the comment from him.
