OK (225 tests, 513 assertions)

[MGatner]

Looks good! What do you think about submitting IntBoolCast to the framework?

[MGatner]

It seems like all our tests are slower than Tachycardia wants; it might be good to increase the base rate so we can actually see which tests are particularly slow.

[kenjis]

It might be slow because of my Docker environment.
Docker on macOS is generally slow.
