Ak!  I literally just finished reading it and wanted to note a lack of clarity on one point. :-)

The signature of the callback is never specified explicitly.  The ternary is a bit confusing.  I assume the signature is 

callable(mixed): bool

But that's not made explicit.  It's also not made explict that omitting the callable collapses to "is truthy".  That's a sensible thing to do, but it's not stated explicitly anywhere, just inferred from the code sample.

I'm not sure if it's safe to clarify at this point as the vote just started.
