I still don't understand what this illustrates.

But, `mapcar' and `apply' are two other cases.
Both take FUNCTIONs as arguments so the sharp quote is
called for, if this method is to be adhered to.

But as for "list", I would say no, calling the
argument that isn't good because as you say, it is
already the name of a common function that people's
eyes are trained to recognize (being something else).
Better to call it "l" or whatever.
