I am not sure "not pulling its weight" in this and also 05/18 is a
fair judgement.  A short helper function sometimes helps readability
by giving an extra abstraction.

But I agree 100% with these two steps that they weren't making them
easier to read.  A raw call to error() shows clearly that we are
reporting an error and more importantly by losing an intermediary
we do not have to wonder at the call site if there is anything else
going on in that "report" function (where there isn't).

Thanks.
