Ability to set multiple values at once

When you need to add multiple values, there is little sense in doing separate operations (and also creating intermediate objects) like:
const a = ImmutableMap([['x', 1], ['y', 2]]);
const b = a.set('z', 3).set('t', 4);It would be nice to have .extend method that would allow to do things like:
const a = ImmutableMap([['x', 1], ['y', 2]]);
const b = a.extend({z: 3, t: 4}); // or a.extend(#{z: 3, t: 4});skrat commented
I believe this is something that can be handled by a merge operation. extend is surely confusing and hugely overloaded term.

@skrat merge also doesn't exist at the moment. I don't care whether it will be called merge, extend or assign, the functionality is what's interesting.

I believe ideas is that spread operator will handle that:
const b = #{ ...a, z: 3, t: 4};
