My point was less about the name and more that I'd prefer not to have
an indirect variable which isn't useful.

That is a bad choice of name now I look at it! I was thinking more
about the use of a function.

I don't really mind the list comprehension directly or a function, I'd
just prefer not to have an indirect variable around to confuse people.
