Ruby syntax when invoking a method

Question

Found this source code on GitHub:

def objects_from_response(klass, request_method, path, options={})
  response = send(request_method.to_sym, path, options)[:body]
  objects_from_array(klass, response)
end

For this specific line:

response = send(request_method.to_sym, path, options)[:body]

What is that [:body] syntax after the method?

Btw, using public_send instead of send is much better if you only want dynamic method calling, not visibility bypassing. — Andrew Marshall

In case it's not obvious, your question applies equally to response = my_method(path, options)[:body]. — Cary Swoveland

send(request_method.to_sym, path, options) returns an object support method [], for example a Hash, then call [:body] on it.
