After spending the better part of the month implementing date support
in RethinkDB, Mike Lucy sent the team the following e-mail. It would
have been funny, if it didn't cause thousands of programmers so much
pain. Read it, laugh, and weep!

So, it turns out that we're only going to support dates between the
year 1400 and the year 10000 (inclusive), because that's what boost
supports.

#define MSDesignatedInitializer(__SEL__) __attribute__((unavailable("Invoke the designated initializer `" # __SEL__ "` instead.")))

// Sample usage:

- (instancetype)initWithObject:(id)object;
- (instancetype)init MSDesignatedInitializer(initWithObject:); // <- This even gets auto-complete.

// Now calling init on this class would throw a warning.
