Date of birth pickers are a surprisingly nuanced UI problem. What do you pick as the initial value? How do you allow users to easily move by large amounts (years) as well as small amounts (the exact day)? Defaulting to today and even allowing future dates is funny though.

I've been building an 'extract function' refactor feature. It's surprisingly nuanced. Where do you put the extracted function? Once you've done the static analysis, what order do you use for the parameters?

Assertions are a surprisingly nuanced design space. In a test, if I assert `x < y`, I really want to see the values of x and y when it fails. Do you define an API for every possible predicate (Python's assertLess, expect.js) or try to support the native syntax (c.f. pytest)?
