Can someone give an example of a "reasonable" function that never uses one
of its parameters, and justify the existence of that parameter in this case,
please?

Because for this example,
f :: _unused -> A -> B
f _ a = b
I think what I'd do is to write the function f without that first parameter,
and call the funcrtion accordingly.

Best,
