Hi Bruce,

I don't like the length of "ignore_value" either, but think of that
as a feature, not a problem.  It's more of an auto-regulator: If I'm
ignoring so many "important" return values that the "ignore_value"
uses impair readability, then I take that as an indication that I'm
doing something wrong.
