If you are trying to advocate for a new feature in bash, it would behoove
you to use an example that ACTUALLY DEMONSTRATES how it would be useful.
Not a bogus example in which the feature is not only unnecessary, but
harmful as well.
All of the discussion I've seen so far points to the proposed new feature
being useful only in interactive shells, to save a tiny bit of typing
when someone is using commands that are quite unusual in interactive mode.
In a script, one would store the filename in a variable, every single time.
