Hmm. I did consider this, but discarded the idea in favor of (in the
future) printing the expression instead. For now I'd like to leave the
directives as they are; once the changes are in, I wouldn't mind someone
adding what you suggest, while I would still keep on my todo list an
item to add the expression printing (perhaps then only when no message
was specified).
