I wouldn't conflate the two purposes. The spell-corrector on its own might have some value, but adding chomp functionality to it diminishes its generality. Also, what is the use case for a return value consisting of the number of words corrected plus the number of characters that chomp removed?

The spell-corrector itself is a big leap of faith. I find that spell-checkers frequently guess incorrectly, particularly in documents that contain a mixture of prose and code or other technical text. While it might be great for the simple case, it's hard to imagine what that simple case would be.
