Ah, not really sure I agree. Yes I suppose in this case because it
has that comment. But you could instead remove the comment and
leave the function there (because the comment is redundant with
the function name), and then your main function is 1 line
instead of 4.
Don't remove functions just because they're called once, if they
are a nice self-contained and well named thing. But okay for here
I suppose.
