Is Equalizer a Good Tool to Document APIs?

Equalizer is able to make the discussion more concrete and more action. Because specs and types are used inside OGP to document API, you may see that some API can be improved. And the type checker can at least support these places, and people start discussing. So, I think that when you start discussing your code, having some tool which provides concrete feedback... It's more actionable than just hand waving discussion.
