Comment (by nacin):

 I disagree with this. One of the best things we can do here is offer
 immediate and loud feedback to a developer in these cases. This is a
 developer error, not a user error. Issuing a warning should raise enough
 alarms without actually terminating execution flow.

 We've all made a typo in a callback, only to spend quite a bit of time
 figuring out what was going wrong. It's worse when the issue is not
 reflected in the logs.

 I'm actually not sure why the NULL check is there. I would rather remove
 it for both meager performance reasons and developer feedback reasons.
