Please can you include a unit test which fails before and passes after?

This exception trap feels perhaps too broad. I'd rather the trap happen narrowly around a line or two. Or maybe there should be a test for orig vs. inflected to detect when split(" ") will not produce compatible arrays. Or even better would be to determine why postprocess would be called with incompatible parameters and disallow that.
