I didn't know that they weren't exported.  Just in the past day, I've been
writing some code that uses the calendar module, annotating it with calendar
types, but as far as I can tell, the compiler doesn't actually care if the
type was actually exported or not.  Which downstream tool is going to throw
the hissy-fit about it?  Dialyzer?
