iex(6)> broadcast_poke same_path("/tests/live/mini"), color: "red"
** (ArgumentError) argument error
    :erlang.apply("same_path:/tests/live/mini", :assigns, [])
    (drab) lib/drab.ex:646: Drab.get_view/1
    (drab) lib/drab/live.ex:441: Drab.Live.do_poke/5

This is because Drab.Live in general requires connection to the browser, as it is getting the current assigns from there.

There are three available solution for this

1. Remove broadcast_poke. Initially, I did not plan to implement it, changed my mind because of Allow to broadcast using poke / peek #60

2. Allow broadcast_poke only with connected socket, create a good error message and fix a documentation (remove "all broadcasting functions may have socket or... as an argument").

3. While broadcasting to non-socket, force to provide all the assign values. In this case there is no need to read the assign values from the browser.
   The only thing is a problematic API, we need to provide the list of other assign values somehow.

broadcast_poke same_path("/"), color: "red", using_assigns: [text: "text",..]

But in this case you can't name you assign @using_assigns :) Any other suggestions?

Personally, I like 1st solution the most :) But 3rd may also do the trick, with good error message when not all the assign values are provided.

Additionally, we could implement 3rd solution also in poke - if you provide all the values there is no need to read it from the browser, which improves the performance, especially when having partials with one assign only.
