Should limit === 0 be supported? Or would Eloquent expect that to be a NOP?

I suppose the notion of limit: 0 meaning "delete all" is an implementation detail of MongoDB's delete command and not a general concept, so I'm fine with not supporting that.

I do wonder if we should have a separate exception message if 0 is specified that advises users to specify null instead (or not call limit() at all), as this message might confuse a user with more experience with MongoDB than Eloquent.

You're absolutely right. I've also banned 0.
