Can be used to merge multiple objects into each other. It will merge the objects recursively,
so if your object looks like {a: {foo:'bar'}} and {a: {bar, 'baz'}} the result will be
{a:{foo:'bar', bar: 'baz'}}.
For the cool part: It works also for Array's, Map's, Set's in any order. So you may merge
a Set with a Map, with an object and you may even nest objects, and Maps into each other.
Arrays will be merged and values will be deduped if they come from different lists.
Meaning: [1, 2, 3] + [1, 4, 6] = [1, 2, 3, 4, 6]
BUT: [1, 2, 3] + [1, 4, 4, 4, 6] = [1, 2, 3, 4, 4, 4, 6]
Note When merging an object into an array or a Set, you will loose your keys!
The first argument type will determine the output type. So, if you supply an object,
followed by an array, the output will be an object.
