lensing objects: L.merge?

[KiaraGrouwstra]

In the spirit of (batch) upsert, I wonder if, not unlike L.append for updating existing arrays, writing to existing objects might have use for something like L.merge (just a lens equivalent of R.merge).
There might be more, but this just stood out to me as a more likely addition to flesh things out.

(Replying with a mobile.) Hmm... Could you give an example of what you have in mind?

[KiaraGrouwstra]

L.merge(['foo'], { b: 2, c: 3 }, { foo: { a: 1, b: 0 } }); // { foo: { a: 1, b: 2, c: 3 } }

That is to say, I'm imagining an existing object structure to get updated based on the values in the provided object.

Hmm... How about this:

L.modify('foo', R.merge(R.__, { b: 2, c: 3 }), { foo: { a: 1, b: 0 } })
// { foo: { a: 1, b: 2, c: 3 } }

Well, that works. Thanks! :)

With PR #104 one could say:

L.assign('foo', { b: 2, c: 3 }, { foo: { a: 1, b: 0 } })
// { foo: { a: 1, b: 2, c: 3 } }

Thanks for the follow-up! That's awesome, looks like object manipulation just got more pleasant. :)
