# There are <tt>before_command</tt>, <tt>after_command</tt>, and <tt>around_command</tt> callbacks
# available to be invoked before, after or around every command received by a client respectively.
# The term "command" here refers to any interaction received by a client (subscribing, unsubscribing or performing actions):
#
# module ApplicationCable
# class Connection < ActionCable::Connection::Base
# identified_by :user
#
# around_command :set_current_account
#
# private
#
# def set_current_account
# # Now all channels could use Current.account
# Current.set(account: user.account) { yield }
# end
