"silently return"ing can be an error.  eg, almond's require(), which
doesn't throw exceptions if you've not define()'d a module, tends to be a
pain in the arse to debug.

Especially for the "core" bits, especially at start up time, we should be
pretty defensive and noisy.  Lost hours a week ago debugging a startup
issue in the core bits.  To figure it out, I had to make the core defensive
and noisy.
