That's not really what I'm talking about at all. Private methods are often useful for handling internal details. But often when you have a lot of private methods, you're bundling too much functionality into one object. I have found that it is very common that I get significant improvements in readability, testability, and comprehensibility when I decompose a large structure with a lot of private methods into a few smaller structures that operate on each others' public API.
