It's possible to reliably segfault Emacs when using undercover, at least on Travis: https://github.com/Wilfred/elisp-def/commit/57523ad268e0f4d2550386d45d55d7a6ed5fe50c
Not sure why at this point.

Trying to let my 3yo try as many different technology interfaces as possible.
Mouse: not too bad, especially after reducing sensitivity.
Keyboard: WASD is easy to lose track of in a sea of buttons.
Controller: requires both hands together, which is tricky. Arguably the left hand is more important too, hard for a right hander.
Further tinkering with diagnostics, following feedback!
* Two lines of context above and below now.
* The caret is included in the line below where possible.
* Syntax highlighting of keywords.
I kinda feel that smart context sizing would be better. What do you think so far?
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)?
