Can we get this reviewed and merged, please? @jenssegers

Thanks!

Do you remember why you needed this method @lindelius?

Both

->where('tags', 'all', ['ssl', 'security'])

and

->whereAll('tags', ['ssl', 'security'])

Produced the same MongoDB query

{ tags: { $all: ["ssl", "security"] } }

@GromNaN Not really. I haven't used the library for years, but it was either because there was no other way to do it back then (6 years ago) or that I just wanted a nicer way to do it than to explicitly have to type the "all" parameter. Most likely the "all" option was either not documented or didn't exist. I really can't remember, though. Sorry.

FWIW, the projects I worked on back then are no longer using the method

Thanks for checking.
