Why not make it fully recursive while you're at it? Nest it all the way down....?

Why not make it fully recursive while you're at it? Nest it all the way down....?

Was thinking about that but I think it's not possible. E.g. set('foo.bar.baz.bla', 2) has two different intents;
a) sub-path: ['bar' => ['baz' => ['bla' => 2]]]
b) indexed by type (e.g. addresses): ['bar' => ['type' => 'baz', 'bla' => 2]]

I'm not even sure the change as it is now doesn't break some edge case I'm missing. I'll give it a second look tomorrow.

Will close this one in favor of #12
