Should path be an array?

[skrat]

I find it pointless to concat and stringify the path, because if one wants to use it (eg. in a getIn call), it has to be parsed. What's the point of having it as string? Yes I do some pattern matching now, using regular expressions, but even that would be faster and more convenient if path would be an array of actual keys.

Right now, for us, it's more convenient that .toJSON() is compatible to the json patch spec, which adopts json pointer strings rather than arrays: https://tools.ietf.org/html/rfc6902

Will talk about it, perhaps could be an options to the diff function.

nice! perhaps we could eventually have a single code base, and an API to support both return types
