Yes, please go ahead. :D
Keep in mind today the autocomplete does not have information about the
evaluator (which is the process that effectively has variable bindings).
However, you can reach the evaluator from the autocomplete code as follows:
{:dictionary, keys} = Process.info(IEx.Server.local, :dictionary)
keys[:evaluator]
You may need to extend the evaluator process (defined in IEx.Evaluator) to
respond to new messages which you will send from the autocomplete.
I assume that as soon as we allow the autocomplete to access information in
the evaluator, we can support both:
map.f<Tab>
some_module.f<Tab>
Please let me know if you have any questions!
