If I have to resort to hole-driven development then it seems like something has gone very wrong? I like to understand the libraries I’m using. Libraries should have good API documentation and intuitive type definitions. I shouldn’t have to carefully study how they’re put together, like solving a math homework problem.

Hole-driven development is especially useful when at the end of the workday your brain is fried, or when you are simply not in a good mood to understand all the type definitions. It allows you to defer your understanding and still make progress.
